to estimate changes in the radiometric response of both sensors. While the 2009 campaign (VCC 2009) indicated significant initial degradation in the sensors compared to the prelaunch values, the results presented here show that the stability of the sensors has improved with time. The largest changes were seen in the 0.76 μm oxygen A-band for TANSO-FTS and(More)
Spatial and temporal variability of atmospheric water vapor (H 2 O) is extremely high, and therefore it is difficult to accurately evaluate the measurement precision of H 2 O data by a simple comparison between the data derived from two different instruments. We determined the measurement precisions of column-averaged dry-air mole fractions of H 2 O (XH 2(More)
Greenhouse gases Observing SATellite (GOSAT) is a Japanese MOE/NIES/JAXA joint program to observe greenhouse gases, such as CO 2 and CH 4 , from space. The GOSAT will be launched in 2008. The GOSAT carries a Fourier transform spectrometer and a push broom imager. The GOSAT development is going on in phase-C/D and characterized the sensor performance in(More)
