The Earth Science Enterprise (formerly Mission to Planet Earth) was
established to use the advanced technology of the National Aeronautics
and Space Administration (NASA) to understand how the land, oceans,
atmosphere, ice caps and life forms interact as a system in influencing
climate change. To accomplish this, NASA is flying a series of Earth
Observation System (EOS) satellites that will take 24 different
measurement suites important to Earth Science research. Additional
data will be taken from smaller, more narrowly focused satellite
missions. The unprecedented volume of data expected from these missions
will be collected, processed, and distributed by NASA's EOS Data and
Information System (EOSDIS).
It is the intent of the Enterprise to promote open access to
its data by the general public, including the academic and industry
communities. This is a fundamental feature of the program. Allowing open
and timely availability to Enterprise data is expected to accelerate
the progress of climate research. As a consequence, more information
will be available to policymakers to make critical decisions relating
to environmental quality, land-use management, and other key policy
areas. In addition, this approach should also help the development of
practical applications and commercial products and services derived from
Enterprise-related data and technology.
This Statement on Data Management (Statement) is intended to guide
the management of scientific data from the Enterprise. The principals
set forth in the Statement are intended to advance the goals, mission,
and vision of the Enterprise and encourage consistent treatment of
data management issues across the Enterprise. They are consistent with
existing statutes, federal executive orders, and NASA's own established
policies.
For the purposes of this Statement, the term "data" shall mean the
research data generated or acquired by the Earth Science Enterprise to
meet Enterprise goals as outlined in the NASA Strategic Plan. This term
shall not include so-called technical data, i.e., specific information
required for the design, development, production, manufacture, assembly,
operation, use, repair, testing, maintenance, or modification of a
product, such as a data collection system (e.g., a satellite, aircraft,
or ground system).
This Statement elaborates on Executive Branch and other legal guidance
for data management by the Earth Science Enterprise. The following eleven
statements summarize the main principles drawn from that guidance.
- NASA shall plan and follow data acquisition policies that
ensure the collection of long-term data sets that will satisfy the
research requirements of the Earth Science Enterprise.
The success of the Earth Science Enterprise depends on data acquisition
practices that will enable the collection of a comprehensive global,
long-term data set to address the research requirements of the Earth
Science Enterprise. NASA adheres to the following principles regarding
data acquisition:
- Data from satellites and other data sources will be acquired
according to priorities recommended by Earth Science Enterprise
participants and confirmed by the Associate Administrator for the Earth
Science Enterprise.
- Where site-specific ( rather than global) observations are made,
data acquisitions will be conducted on a demand basis. In these cases,
data will only be taken where there is: a) an identified user who has
requested and will analyze the data or b) recognition of a future Earth
Science Enterprise need for the data.
- The level of processing and preprocessing will be dictated
by the scientific requirements of the Earth Science Enterprise, using
peer-reviewed algorithms.
- NASA is committed to the full and open sharing of the Earth
Science data obtained from U.S. Government-funded and -owned systems
with all users as soon as such data become available. All Earth System
Enterprise missions, projects, and grant proposals shall include data
management plans to facilitate implementation of this principle.
NASA's Earth Science Enterprise is a bold effort to apply advanced
satellite and computing technologies to answer fundamental questions about
how the land, seas, air, and life interact as a system and how human
activity impacts our environment. To meet this challenge, there must
be full and open sharing of the data from the Earth Science Enterprise
with the research community, private industry, academia, and the general
public. The greater the availability of the data, the more quickly and
effectively the user community can utilize the information to address
basic Earth Science questions and provide the basis for developing
innovative practical applications to benefit the general public.
Under most circumstances, the full suite of government-owned data
sets within the Earth Science Enterprise shall be made available to
all users, with no user group or group of users receiving a period of
exclusive access. Access will not be limited to the scientists, managers,
or principal investigators working with the Earth Science Enterprise,
but will be extended to the full scientific community and the general
public. This principle applies to all Earth Science Enterprise activities,
including satellite missions, field campaigns, and grants.
There may be practical impediments to providing timely access to
Earth Science Enterprise data held by certain user groups, particularly
data used in smaller projects at the principal investigator level. These
projects may lack the time, staff, and resources to ensure the earliest
public availability of their data product. Nevertheless, even in such
difficult cases, NASA is committed to providing the earliest feasible
data distribution, provided the requester pays for the marginal cost of
dissemination. Further, NASA shall require, in advance, data management
plans for all Earth Science Enterprise missions, projects, and grant
proposals to help assure that sufficient resources are available for
data management at all the Earth Science Enterprise levels.
- For data from government-owned or -funded systems, NASA
will enforce a principle of non-discriminatory access so that all users
within the same data-use category will be treated equally. Preferential
treatment for U.S. government users and their affiliates will be allowed
where expressly permitted by law.
NASA is committed to providing access on a non-discriminatory basis to
all types of scientific data from the Earth Science Enterprise, neither
favoring or disfavoring any user or class of users. Non-discriminatory
access shall be a requirement for any mission in which NASA resources are
invested. That principle is already specifically mandated for unenhanced
data from government satellite systems by the Land Remote Sensing Policy
Act of 1992, 15 U.S.C. §5601 et seq., which specifically requires
that such data be made available to all users on a non-discriminatory
basis. Section 501(a) of that Act states:
Except as provided in subsection (b) of this section, any unenhanced
data generated by the Landsat system or any land remote-sensing funded
and owned by the U.S. Government shall be made available to all users
without preference, bias, or any other special arrangement [except on
the basis of national security concerns] regarding delivery, format,
pricing, or technical considerations which would favor one customer or
class of customers over another.
However, subsection (b) of Section 501 does allow for preferential
treatment for the U.S. government and its affiliated users provided
that the data from these government satellite systems are used for
non-commercial purposes.
For the purposes of this Statement, the term "non-discriminatory
basis" shall mean that all users in a clearly defined data-use category
can obtain data on the same terms and conditions, and the categories
are defined in such a way that potential users will be included in
each category.
- NASA shall make data from the Earth Science Enterprise
available at a reasonable price to facilitate access and encourage
use. Data from NASA and its U.S. government partners shall be priced at
the cost of dissemination or, in cases where such pricing would unduly
inhibit use, below cost. For data from industry and forien partners in the
Earth Science Enterprise, pricing and access policies shall be established
by negotiation between NASA and the relevant Earth Science Enterprise
provider and system operator. NASA will seek to ensure pricing and access
policies consistent with the principles in this Statement.
Cost can be one of the greatest barriers to broad access to data
by the general scientific community, as well as the public and private
sectors. For that reason, making data available at a reasonable cost is
necessary to facilitate scientific and other uses of the agency's Earth
Science data. Accordingly, within the limits of current law, NASA will
endeavor to make data available at a price that does not unduly inhibit
its use.
For all data from NASA and other U.S. government sources, the data
will be made available, without regard to the intended use of the
data. Applicable federal law and policy allow the federal government to
charge less than the cost of dissemination if the true cost inhibits
use of the data. NASA may, under special circumstances as determined
by the Associate Administrator or his designee, provide data to users
at a nominal cost or at no cost where at-cost pricing would inhibit
use. NASA appreciates that below-cost pricing may, in some cases,
have the potential to impair the ability of federal agencies to defray
their operational costs and encourage users to request more data than
they actually need. Therefore, in deciding whether to permit below-cost
pricing in particular cases or situations, the Associate Administrator
shall carefully weigh the benefits of the discount pricing to the user
community against the potential costs to affected federal agencies.
It should be emphasized that, since data must be distributed on
a non-discriminatory basis, all data products must be available to
all persons in the same data-use-category at the same price. However,
this requirement does not preclude traditional pricing arrangement,
such as volume discounts, so long as these arrangements are offered on
a non-discriminatory basis.
For data acquired from industry and foreign partners in Earth Science
Enterprise activities, a pricing and access policy will be negotiated
with the relevant data provider and system operator. NASA will seek to
ensure consistency in negotiated pricing and access policies. In that
regard, pricing of data from commercial and international partners shall
be guided by the applicable provisions of this Statement concerning
commercial data purchases, cooperative activities with industry, and
international cooperation.
- All data required for long-term global change research shall
be archived. Data archives shall include easily accessible information
about dta holdings, including quality assessments, supporting relevant
information, and guidance for locating and obtaining the data.
The archiving of long-term sets of global climate data is critical
for the meaningful study of Earth science and the understanding of
important environmental and climate questions. Archives must provide
easily accessible information about data holdings, including descriptive
metadata, quality assessments, supporting ancillary information, and
assistance in locating and obtaining the data.
Each Earth Science Enterprise data set shall be subject to peer
review to determine its merit for long-term archiving. In the event that
lon-term archiving is deemed appropriate, NASA shall seek guidance from
Government agency partners to determine if such requirements can be most
effectively met through interagency cooperation.
Consideration for long-term archiving shall include: a) all
data acquired by, or in support of, Earth Science Enterprise-funded
research projects; b) all data acquired systematically by Earth Science
Enterprise-funded missions for the purpose of documenting long term
variability; and c) all accessible data concerning natural disasters and
other extraordinary events identified by the Earth Science Enterprise
(e.g., volcanic eruptions, floods, and forest fires).
The Earth Science Enterprise shall not normally archive data taken
systematically for the purpose of documenting long-term variability if
those data are already being archived by a partnering agency such that
long-term access by NASA is assured. This principle shall apply to data
from NASA missions as well as joint missions undertaken with another
agency or institution, either domestic or foreign. However, NASA may
decide to archive such data if it receives a specific request and, upon
agency review of the request against NASA's mission, that request is
granted. Further, should the archiving institution decide to close its
archive, the Earth Science Enterprise may consider the acquisition of all
or part of the archived data, but shall not make such acquisition unless
it is cost-effective and satisfies NASA's scientific requirements.
- Where cost-effective, NASA shall make purchases of
commercial data to meet the scientific objectives of the Earth Science
Enterprise. Data purchase arrangements should, at a minimum, permit
appropriate use, distribution, and duplication of the data for Earth
Science Enterprise purposes by all researchers affiliated with the Earth
Science Enterprise. NASA may purchase data on behalf of, and through,
other federal agencies for research and investigation purposes.
NASA's Commercial Strategy for the Enterprise states that the agency
shall "seek cost-effective science data opportunities that meet the
science objectives of the Earth Science Enterprise" In implementing this
goal, NASA shall -
- establish rights to distribute proprietary science data purchased
from commercial sources (rather than acquired through Earth Science
Enterprise capabilities) according to terms mutually acceptable to
NASA and the commercial sources coming as close to NASA's goal of
non-discriminatory access as possible
- seek out data purchase agreements with commercial sources where
NASA is not the dominant customer over the long term
- act as a data purchasing agent for other federal agencies for
research and investigation purposes and encourage other agencies to
serve as purchasing agents for NASA for such purposes
These principles will serve the scientific goals of the agency and
the federal government, as well as the public interest. In the long run,
such commercial data purchases could potentially reduce agency costs by
precluding the need to design, develop, and launch spacecraft to collect
needed Earth science data from space and streamlining data acquisition
procedures and procurement processes. Eventually, the evolution of a
vigorous commercial space data industry may enable the collection and
access of more Earth Science data than is gathered today, with benefits
to NASA and other potential customers derived from more-competitive
pricing and broader data selection.
In entering into data purchase arrangements, NASA shall negotiate
data purchase arrangements which, at a minimum, permit appropriate use,
distribution, and duplication by Earth Science Enterprise researchers for
science purposes. Such researchers include: a) researchers affiliated with
the Earth Science Enterprise through interagency data exchanges, grants,
and other formal mechanisms and b) researchers in the international
community with whom NASA has formal data-exchange arrangements or formal
understandings. NASA will also seek to negotiate terms that would allow
the release of data to users outside the Earth Science Enterprise
researcher community, particularly for scientific, educational, and
other non-commercial uses, at the cost of dissemination. NASA shall seek
agreement with the data provider on the degree to which the public will
be allowed access to the data via the Internet.
The government has the duty to facilitate access to publicly
funded data - the more the federal investment, the greater
the government's duty to preserve or retain broad access to the
data. Where the U.S. taxpayers, through the federal government, have
made a considerable investment in the observing system of data product,
unreasonable restrictions on use or availability by federal government
agencies or their affiliates will not be accepted.
- For each cooperative activity with industry, domestic
or foreign, NASA shall seek agreement on all major data-management
and distribution issues durin the project-definition phase. The
respective contributions of the parties to the activity shall be
considered in allocating rights and control over the results from the
activity. NASA shall seek to ensure meaningful use of the data for
Earth Science Enterprise purposes by all researchers affiliated with
the Enterprise.
The Enterprise regularly engages in cooperative activities with
industry partners, domestic and foreign, which may take many forms. From
the perspective of the Earth Science Enterprise, the ultimate goal of
such cooperation is to obtain cost-effective, scientifically meaningful
data to help meet Enterprise objectives. Therefore, the management and
distribution of data from such cooperative projects must be a central
issue in the project definition phase, and agree ment on these matters
should be achieved before the projects are undertaken.
With these interests in mind, NASA shall adhere to the following
principles regarding data from join missions and projects with
industry:
All matters pertaining to data management, particularly data rights and
data distribution responsibilities, shall be resolved between NASA and
the industry partner prior to undertaking the cooperative NASA-industry
activity. NASA shall endeavor to negotiate agreements with the industry
partner to assure as broad an access to data from the cooperative activity
as possible. NASA shall define the distribution, use, and and archiving
requirements for each mission in advance and ensure that the the agreement
with the commercial partner meets those needs. The respective contribution
of the partners should be taken into account in allocating rights and
control to the results of the cooperative activity. In cases where data
are provided on different term for commercial and non-commercial use, NASA
should encourage the commercial partner to be responsible for meeting the
needs for commercial use and should focus agency resources on meeting the
research and applications community requirements associated with the Earth
Science Enterprise's mission. NASA shall assure meaningful use of data
from cooperative activity for Earth Science Enterprise purposes by all
researchers affiliated with the Earth Science Enterprise. This includes
access to raw data as a part of the scientific peer review process.
- NASA shall engage in ongoing cooperation with other federal
agencies, particularly with those involved with space-based activities
or Earth Science research, to increase the effectiveness and reduce
the cost of the Earth Science Enterprise. This interagency cooperation
shall include: sharing of data from satellites and other sources, mutual
validation and calibration of data, and consolidation of duplicative
capabilities and functions.
NASA continues to join with other federal agencies in cooperative
activities that advance the goals of the Earth Science Enterprise. To
maximize the benefit of this cooperation, NASA seeks input from
cooperating agencies when determining requirements and priorities
for data acquisition. In advancing the interests of the Earth Science
Enterprise, NASA provides its federal agency partners with access to
Earth Science Enterprise data. Further, NASA supports interoperability
of systems and compatibility of standards to facilitate data sharing
and exchanges. Finally, NASA cooperates with other federal agencies
in developing the most cost-effective policies for long-term data
archiving.
- NASA shall, in compliance with applicable federal law
and policy, negotiate and implement arrangements with international
partners, with an emphasis on meeting the Nation's own data acquisition,
distribution, and archival needs.
Cooperative activities with international partners often present unique
circumstances because of the different laws and policies that govern
each country. The management of the data resulting from international
cooperative projects is ultimately determined by respective project
participants, whose goals, policies, and constraints may be quite
different. Nevertheless, in negotiating with its foreign partners, NASA
will seek to reach agreements and understandings that are in harmony
with applicable federal law and policy, as well as with the principals
contained in this Statement, and meet the needs of the agency.
When entering into any international project, NASA must ensure that its
own data acquisition, distribution, and archival needs are defined and
met by the terms of the agreement. In general, international agreements
involve no exchange of funds with each party making in-kind contributions
of products and services. The benefits to NASA from these arrangements may
come in several forms, but typically access to valuable scientific data
is one of the primary incentives for agency involvement. Accordingly,
it is critical that these agreements explicitly address data policy,
specifically each party's rights and responsibilities for data acquisition
(including tasking and operations), distribution, and archiving.
All international agreements should clearly address basic questions
regarding the rights and responsibilities of the parties with respect
to:
- Data acquisition and tasking. If data acquisition is
not global and continuous, who decides when the instruments are on,
and where the data are transmitted to the ground and collected? Who pays
for the operational activities?
- Data distribution and use. Who may access the data,
on what terms, through what facilities, using what standards? Whose
consent is required, if any, for access?
- Data archival. What data will be archived for how long,
at whose expense, in what facilities, and under what conditions? Who
ha access, and on what terms, to data in the long-term archive? How are
data eventually disposed of?
Given the investment of federal government resources in cooperative
missions, NASA should endeavor to ensure that all data are available
to all users under defined conditions (i.e., any use should be able to
determine what data exist and to access them in a reasonable manner,
whether directly or through a third-party distributor). This principle
should ensure nondiscriminatory access in the sense that no user is
denied access to data (except for reasons of national security or public
safety). In general, for missions involving significant NASA investment,
NASA shall insist that a long-term archive for mission data be defined
and that provisions are made for its funding.
As a minimum requirement for any mission, NASA-affiliated users should
be able to obtain and use data from cooperative missions. Their rights
should be defined broadly enough to include applications demonstrations as
well as more basic research investigations, and should not be limited to
NASA-funded investigations, since NASA conducts cooperative science with
foreign scientists and with investigators funded by other U.S. Government
agencies such as the National Science Foundation. The relevant Earth
Science Enterprise and project science leaders need to be part of the
agreement and negotiating process to assure that specific terms are
included in the international agreements to promote the realization of
mission objectives. Furthermore, access to data should be made as broad
and inexpensive as possible to facilitate maximum utilization by the
scientific community.
- NASA may allow for exceptions to the guidance contained in
this Statement on a case-by-case basis where permitted by law and in
the furtherance of the public interest.
The guidance in this statement with regard to open, non-discriminatory
public access to Earth Science Enterprise data is fundamental to the
mission of the Enterprise. Nevertheless, NASA recognizes that, to
the extent permitted by law, it may be in the public interest for the
Associate Administrator tp grant exceptions from the principles in this
Statement on a case-by-case basis. Past experience suggests most cases in
which exceptions might be entertained would likely involve either: a) data
acquisitions for commercial sources or joint missions with industry or b)
international partnerships. In these categories of cases, it is sometimes
determined that the departures from agency policy are outweighed by the
value of the data, foreign policy, or public policy considerations.
With regard to acquiring data from commercial sources, it may
be necessary to accept seller-imposed restrictions on the use and
distribution of acquired data that would not be appropriate for
government-generated data. For example, in one past case, a commercial
provider contracted to sell remote-sensing data to NASA on the condition
that: a) the data be used exclusively for research purposes and b)
the data be provided to NASA on a two-to-four week delay (to protect
commercial sales of real-time data) except where there is a compelling
research requirement for real-time use by specified users.
Data acquired through data exchanges or joint missions with foreign
partners may also require acceptance of restrictions on data use on
data use and distribution in conflict with NASA policy. In international
arrangements, where the non-U.S. party has made a substantial investment
in the joint activity, that part may have more negotiating leverage
to insist on a restrictive data policy that NASA desires. In such
situations, if, on balance, the activity still advances NASA's mission
goals, a decision could be made to proceed nonetheless. To that end, past
agency practice can be instructive in reviewing individual cases. For
instance, in one joint satellite mission involving NASA and a foreign
space agency, the governing Memorandum of Understanding gave designated
mission investigators a period of three months exclusive access to the
satellite data. Following the period of exclusive access, the data would
be placed in an archive and made available to the general public at no
more that the cost of filling the user request.
In every case where an exception is requested, NASA will attempt to
adhere to the principles in this Statement as closely as possible and
will balance the right of the public to open non-discriminatory access
to scientific information from federal agencies against the asserted
interests of the parties requesting the exception.
- NASA shall review and, if warranted, update this Statement
as a part of the biennial review of the Earth System Enterprise.
NASA will regularly review and, if warranted, update this Statement
as a part of NASA's comprehensive biennial review of the Earth System
Enterprise. Review of this statement will will examine whether
its principles require revision to reflect changes in applicable
law, Administration policy, NASA policy, or relevant facts and
circumstances. The review shall also examine possible revisions to
this Statement that might improve the Earth Science Enterprise's data
management and its ability to carry out its goals and missions. The
Associate Administrator must approve any revisions to the Statement.
