! ! CRTM_VISsnowCoeff ! ! Module containing the shared CRTM visible snow surface emissivity ! data and their load/destruction routines. ! ! PUBLIC DATA: ! VISsnowC: Data structure containing the visible snow surface ! emissivity data. ! ! SIDE EFFECTS: ! Routines in this module modify the contents of the public ! data structure VISsnowC. ! ! RESTRICTIONS: ! Routines in this module should only be called during the ! CRTM initialisation. ! ! CREATION HISTORY: ! Written by: Paul van Delst, 20-Jan-2012 ! paul.vandelst@noaa.gov !
