GOSAT Series
Research Announcements

The Greenhouse gases Observing SATellite (GOSAT) has been observing global atmospheric greenhouse gases steadily even today in the eleventh year since its launch in January 2009. The successor, GOSAT-2 was launched on October 29, 2018 and has started its nominal operation in February 2019.

Given this situation, the Research Announcement on Greenhouse Gases Observing Satellite Series has started newly since 2018 to solicit research proposals utilizing GOSAT and GOSAT-2 data from the public. The third GOSAT RA was released and is now open for proposal submission.

If you plan to conduct research using GOSAT and GOSAT-2 data, please read the following documents carefully and send your research proposal and application documents to GOSAT RA Secretariat by the due date. We are really looking forward to receiving your original proposals.

  • Schedules for the 3rd GOSAT RA
  • Issue of Research Announcement: Friday, November 13, 2020
  • Proposal Submission Deadline (initial): Friday, January 15, 2021
  • Notification of Selection Results (initial): Friday, April 30, 2021 or later
  • Proposal Submission Deadline (after extension): Monday, March 15, 2021
  • Notification of Selection Results (after extension): Friday, June 11, 2021 or later

We appreciate all the researchers who submitted their research proposals in response to the third Research Announcement on Greenhouse gases Observing SATellite Series (the 3rd GOSAT RA). All proposals were peer-reviewed and then evaluated by the GOSAT RA Selection and Evaluation Committee. Here, we would like to announce that the Japan Aerospace Exploration Agency (JAXA), the National Institute for Environmental Studies (NIES), and the Ministry of the Environment of Japan (MOE) have jointly decided to adopt three new research proposals to carry out joint research. Note that the list shown below also includes two proposals that were submitted prior to the extension of the application period and adopted in August 2021.
