Reporting• Interim reporting
The PI shall report on the progress of his/her research in the way designated by
the Three Parties(JAXA / NIES / MOE) at GOSAT‐related workshops as well asinterim report meetings.
In addition, if the Committee deems the research purpose or data application ofthe RA Investigators as deviant from the initial research plan or in breach of thejoint research contract, as a result of the examination of the progress reported,
the Three Parties may terminate the said agreement.

• Final reporting
All PI’s are required to submit the final reports to the Three Parties, inaccordance with the instructions provided in the contract, generally in one year
from the last interim report meeting. The reports shall be prepared in English.
Moreover, the PI’s must present their research results in whole or in part atconferences, symposiums, and workshops to be held by the Three Parties.

PI’s Rights
The PI shall be entitled to the following rights:
1. Submitting requests for new data acquisition necessary forthe implementation of the research on the selected theme.
2. Requesting a delivery of standard products, free of charge,
before the release to the public.
3. Requesting a delivery of research products free of charge.
(Note that the number of such requests will be determined inconsideration of the conformity to the research purpose.)(*) The research products will be made available to RA Investigators, to an
extent necessary for their respective researches, at suitable timing. The
Three Parties do not guarantee product quality.
