GOSAT Series
Research Announcements

The Greenhouse gases Observing SATellite (GOSAT) has been observing global atmospheric greenhouse gases steadily even today, in the tenth 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 Second Research Announcement on Greenhouse gases Observing Satellite Series (2nd GOSAT RA) has issued to solicit research proposals utilizing both GOSAT and GOSAT-2 data.

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 the GOSAT RA Secretariat by the due date. We are really looking forward to receiving your original proposals.

  • Schedules for the 2nd GOSAT RA
  • Issue of Research Announcement: Monday, October 21, 2019
  • Proposal Submission Deadline: Friday, January 3, 2020
  • Notification of Selection Results: Friday, March 6, 2020 or later

We appreciate all the researchers who submitted their research proposals in response to the second Research Announcement on Greenhouse gases Observing SATellite Series (the 2nd GOSAT RA). All proposals were evaluated by the GOSAT RA Selection and Evaluation Committee based on reviews by professionals, and we would like to inform you 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 eight research proposals listed below to carry out joint research.
