1 Applicable Data Policies

The following three policies are applied to the reception, processing and distribution of ADEOS data.

(1) Policy on the Distribution and Reception of Earth Observation Satellite Data (July, 1992)
This policy stipulates a two tier system for the reception and distribution of data observed by the NASDA:S earth observation satellite: one for research purposes and another for general purposes. The marginal cost is charged for the distribution and reception of data for research purposes while market prices are imposed for the distribution and reception of data for general purposes.

(2) E0-ICWG Data Exchange Rules (1993)
The essential objectives of the IEOS Data Exchange Rules are the creation of the IEOS with the ADEOS, TRMM, EOS, NOAA and ENVISAT-1 and the provision of satellite data for non-commercial use (research, applied research and regular use for public services) at the lowest possible cost.
Ten organizations have, in principle, agreed to the rules. These include space station implementation organizations (Science and Technology Agency, NASA, ESA and Canadian Space Agency) and 6 related organizations (NASDA, MITI, Environmental Agency, Meteorological Agency, NOAA and EUMETSAT).
 

[E0-ICWG: IEOS Data Exchange Rules]

The rules consist of 10 items as outlined below.

(i) All IEOS Data will be available for peaceful purposes to all users on a non-discriminatory basis and in a timely manner.

(ii) There will be no period of exclusive data use. Where the need to provide validated data is recognized, any initial period of exclusive data use should be limited and explicitly defined. The goal should be release of data in some preliminary form within three months after the start of routine reception of instrument data.

(iii) All IEOS Data will be available for the use of each of the Agencies and its designated users at the lowest possible cost for non-commercial use into following categories; Research, Applications, and Operational Use for the Public Benefit.

(iv) Agencies which designate users for Research Use and for Applications Use will do so through an Announcement of Opportunity or similar process.
The designation will include a definition of the data to be provided.
Research Users shall be required to submit their results for publication in the scientific literature and Applications Users shall be required to publish their results in technical report and both shall be required to provide their results to the designating Agency and to the Data Providing Agency.

(v) Any of the Agencies may designate national users of the respective countries or Member States of the Agencies as it deems appropriate to be given access to all IEOS data at the lowest possible cost for Non-commercial Operational Use for the Public Benefit, provided the designating Agency assumes responsibility for ensuring that all the terms and conditions for
data use are met. This use will have to be reported to the Data Providing Agency on the basis of commonly agreed criteria including type, usage, and final designation of the data. Designation of users outside the national territory of the Agencies or their member states (e.g., international organizations and agencies in non-participating countries) for Non-commercial Operational Use for the public Benefit will be done only with the agreement of the Data Providing Agency.

(vi) For types of use other than 3 above, the specified data will be made available in accordance with terms and conditions to be established by the Data Providing Agency.

(vii) Each Data Providing Agency will fulfill the data requests of the other Agencies and their designated users to the maximum extent possible. In the event that these data requests exceed the Data Providing Agency's capacity,
the Data Providing Agency and the designating Agency will pursue alternative arrangements to fulfill such requests.

(viii) A11 data required by the Agencies and their designated users will be made available on condition that the recipient agrees to applicable intellectual property rights terms and conditions and/or proprietary rights consistent with these Data Exchange Principles, and ensures that the data shall not be distributed to non-designated parties, or used in ways other than those for which the data were provided without the written consent of the Data Providing Agency.

(ix) Any of the Agencies may delegate some of its functions to other entities; in which case, such Agency will remain responsible for ensuring compliance with these Data Exchange Principles.

(x) Agencies will harmonize criteria and priorities for data acquisition, achieving, and purging, in consultation with other relevant organization.

(3) CEOS Data Exchange Rules (1992)
At the general meeting held in 1 992, the CEOS adopted the Data Exchange Rules to assist research on global changes. The basic objective of the rules is to maximize the use of satellite data, mainly by means of establishing a
mechanism to exchange/share the observation data of earth observation satellites among CEOS members to assist research on global changes and also to eliminate the monopolisation of data by organizations.
 

[CEOS Data Exchange Rules to Assist Research on Global Changes]

The rules consist of 7 items as outlined below.

(i) Preservation of all data needed for long-term global change/climate and environmental research and monitoring is required.

(ii) Data archives should include easily accessible information about the data holding, including quality assessment, supporting ancillary information, and guidance and aids for locating and obtaining the data.

(iii) International standards - including those generated by the CEOS Working Group on Data - should be used to the greatest extent possible for recording/storage media and for processing and communication of datasets.

(iv) Maximizing the use of satellite data is a fundamental objective.　 An exchange/ sharing mechanism among CEOS Members is an essential first step to maximize use.

(v) Non-discriminatory access to satellite data by non-CEOS Members for global change/climate and environmental research and monitoring is essential. This should be achieved within the framework of the exchange and sharing mechanisms set up by CEOS Members.

(vi) Programs should have no exclusive period of data use. Where the need to provide validated data is recognized, any initial period of exclusive data use should be limited and explicitly defined. The goal should be release of data in some preliminary form within 3 months after the start of routine data acquisition.

(vii) Criteria and priorities for data acquisition, archiving, and purging should be harmonized.
 

2 ADEOS Data Reception, Processing and Distribution Policies

Arrangements are in progress to establish the following reception, processing and distribution policies for ADEOS earth observation data.

(1) Reception
/The NASDA will acquire global observation data from the ADEOS with the assistance of overseas reception stations.
/Other organizations will be allowed to receive AVNIR observation data as the AVNIR is a sensor designed to obtain regional data.
/Assistance will be provided for the direct reception of OCTS observation data by general users. /In principle, the direct reception of AO sensor data will not be possible as these data are global observation data.

(2) Processing
/The NASDA will conduct the processing of AVNlR and OCTS data.
/In the case of AO sensor data, distribution will be made by the NASDA as well as by the AO sensor providers.
