The Greenhouse Gases Observing Satellite-2 (GOSAT-2), also known as Ibuki-2 (Japanese: いぶき2
Comparison to GOSAT
[edit]Major changes in comparison to the previous GOSAT are:[4]
- Improved measurement precision.
- FTS-2 can also monitor carbon monoxide (CO) and nitrogen dioxide (NO2).
- FTS-2 can select cloud-free point automatically for observation.
- While GOSAT's CAI was observing nadir view, GOSAT-2's CAI-2 observes forward (20 degree) and backward (20 degree) simultaneously.
- CAI-2 can also monitor PM2.5 and black carbon.[1]
Successor: GOSAT-GW
[edit]As of November 2023[update], GOSAT-GW, the successor of GOSAT-2 and GCOM-W "Shizuku", is under development for launch in JFY2024 on the last flight of the H-IIA launch vehicle.[5]
