About GOSAT
GOSAT (Greenhouse gases Observing SATellite) is an environment-monitoring satellite developed by Japan which launched on 23 January 2009 and remains operational.
It is part of ESA's Third Party Missions Programme, in which ESA has an agreement with JAXA to distribute data products from the mission.

GOSAT Objectives
GOSAT is a JAXA mission within the GCOM (Global Change Observation Mission) programme of Japan designed to monitor the global distribution of carbon dioxide and methane.
GOSAT Instruments
Thermal And Near infrared Sensor for carbon Observation - Fourier Transform Spectrometer (TANSO-FTS)
TANSO-FTS measures the scene radiance of solar short wave infrared spectra (SWIR) reflected on Earth's surface.
| Purpose | Measurements of CH4, CO2, H2O, O2, O3 and aerosol |
| Orbit Type | Sun-synchronous |
| Short Description | 4–band interferometer (3 in NIR/SWIR, 1 in TIR) |
| Scanning Technique | Cross-track mechanical pointing, swath 790 km |
| Resolution | 10.5 km at s.s.p. |
| Coverage/Cycle | Global coverage in 3 days |
Thermal And Near infrared Sensor for carbon Observation - Cloud and Aerosol Imager (TANSO-CAI)
TANSO-CAI is a radiometer to retrieve clouds and aerosol characteristics for more accurate TANSO-FTS data retrieval.
| Purpose | Cloud and aerosol observation |
| Orbit Type | Sun-synchronous |
| Short Description | 4-channel UV/VIS/NIR/SWIR radiometer |
| Scanning Technique | Push-broom, 2000 pixel/line (three VNIR channels), 500 pixels/line (SWIR channel); 1000 km swath |
| Resolution | 0.5 km in UV/VIS/NIR (Channels 1-3) 1.5 km in SWIR (Channel 4) |
| Coverage/Cycle | Global coverage in 3 days |
| Swath Width | 1000 km for UV/VIS/NIR (Channels 1-3), 750 km for SWIR (Channel 4) |
Non-scientific measuring instruments
A total of eight CAMs are being accommodated at strategic locations on GOSAT with the objective to monitor the spacecraft exterior in orbit.
(Technical Data Acquisition Equipment): TEDA is onboard space environment measurement system with the objective to monitor the orbital radiation environment.
