Channel selection for water vapor retrieval

Remote sensing of atmosphere is changing rapidly thanks to the development of high spectral resolution infrared. space-borne sensors. The aim is to provide more and more accurate information on the lower atmosphere, as requested by the World Meteorological Organization (WMO), to improve reliability and time span of weather forecasts plus Earth's monitoring. In this paper a new channel selection strategy for water vapor is presented and analyzed both on simulated spectra and on real spectra.
