Paper Abstract

Broad band radiance measurements at top of the atmosphere are simulated using two diverse line-by-line codes for a number of standard atmospheric conditions to evaluate the sensitivity of broad band spectral and spectrally integrated radiometry to realistic changes of water vapor content in the troposphere and of other parameters of climatic significance. . It is shown that the rotational band is very sensitive to realistic changes in upper tropospheric water vapor. Moreover our ability to retrieve middle and upper troposphere H2O is enhanced if spectral measurements in the water vapor rotational band are compared to measurements in the strong 6.3 micrometers vibrational band, which has been used exclusively since the early 1970's.
