First we discuss the range of satellite data being used in the operational NCEP global forecast system. Then experiments showing the benefit of using hyperspectral radiance data, available in real-time from the AIRS instrument, in systems already using the full operational data base, are reviewed. Effective methods of data thinning and noise reduction are noted. The importance of using the full spatial resolution of the data used is documented. The importance of channel selection for NWP is shown. We also describe the current use of variable hyperspectral emissivity over the entire globe and related studies. We also note a number of methods being used to detect cloud in hyperspectral fields of view. Finally, note is made of the benefits to be gained by the enhanced use of hyperspectral data in NWP and some discussion is provided on desirable characteristics for infrared sounders related to their efficient application to NWP.
