Greenhouse Gases Observation from the GOSAT Satellite
Abstract
The Greenhouse gases Observing Satellite (GOSAT) is a satellite to monitor the carbon dioxide (CO2) and the methane (CH4) globally from orbit. The two instruments are accommodated on GOSAT. The Greenhouse gases Observing Sensor is a Fourier-Transform Spectrometer (FTS), which detects gas absorption spectra of the solar short wave infrared (SWIR) reflected on the earth_fs surface as well as of the thermal infrared (TIR) radiated from the ground and the atmosphere. The FTS is capable of detecting three narrow bands (0.76, 1.6, and 2 micron) and a wide band (5.5-14.3 micron) with 0.2 cm-1 spectral resolution. The cloud and aerosol sensor is an imager of ultraviolet (UV), visible, and SWIR to correct cloud and aerosol interference. The presentation includes the instrument design, pre-launch calibration and onboard calibration schemes; as well as, some test results using the Bread Board Model (BBM).
