GOSAT搭載温室効果ガス観測センサ（TANSO-FTS）短波長赤外バンドのデータ処理手法

抄録

Greenhouse Gases Observing Satellite (GOSAT) will observe infrared light reaching its sensors from the earth's surface and the atmosphere and give spectra which can be used to derive the column abundances of carbon dioxide and methane. The observation instrument onboard the satellite is called the Thermal And Near-infrared Sensor for carbon Observation (TANSO). TANSO is composed of two sensors : a Fourier Transform Spectrometer (FTS) and a Cloud & Aerosol Imager (CAI). This article describes characteristics of data from each band of TANSO-FTS, atmospheric radiative transfer of the input signal to the sensor, and outline of the data retrieval algorithms of the Short Wavelength Infra-Red (SWIR) bands of TANSO-FTS.
