! ! CRTM_IRwaterCoeff ! ! Module containing the shared CRTM infrared water surface emissivity ! data and their load/destruction routines. ! ! PUBLIC DATA: ! IRwaterC: Data structure containing the infrared water surface ! emissivity data. ! ! SIDE EFFECTS: ! Routines in this module modify the contents of the public ! data structure IRwaterC. ! ! RESTRICTIONS: ! Routines in this module should only be called during the ! CRTM initialisation. ! ! CREATION HISTORY: ! Written by: Paul van Delst, 04-May-2012 ! paul.vandelst@noaa.gov !
