Abstract

TANSO-FTS (Thermal And Near infrared Sensor for carbon Observation Fourier Transform Spectrometer) and TANSO-CAI (Cloud and Aerosol Imager) are a space-born optical sensor system mainly oriented for observation of greenhouse gases (GHGs). TANSO will be installed on the Greenhouse gases Observing SATellite "GOSAT" and launched in early 2009. The TANSO-FTS is a Fourier transform spectrometer which has 3 SWIR bands (0.76, 1.6 and 2.0 μm) and 1 TIR band (5.5 - 14.3 μm) for observation of scattering light and thermal radiation from the earth, mainly focused on CO₂ absorption spectra. The TANSO-CAI is an imager for detection and correction of clouds and aerosol effects to determine GHGs quantities. The instrument characteristics of TANSO-FTS are high SNR (~300), quick interferogram scan (1.1 ~ 4.0 s) with moderate wave-number resolution (~0.2 cm^-1), and polarization measurement. Now, integration and test of proto-flight model of TANSO have been completed. In this paper, the results of performance test such as SNR, ILS, polarization sensitivity, etc. are described.
