Paper Abstract

The expressions are derived for both the sensitivity of retrieved surface pressure and that of radiance measurement to atmospheric temperature profile in detail. Calculations indicate that the later should not be regarded as one of bases for channel selection. After removing channels with very large maximal relative fitting errors of atmospheric transmittance model and mean transmittance model, weak absorption channels and channels with higher sensitivity of retrieval surface pressure to atmospheric temperature profile, the remote sounding accuracy of surface pressure with 1000 hPa is improved by about 3.2~21hPa.
