C**** C ************************ C * OASIS MODULE * C * ------------ * C ************************ C**** C*********************************************************************** C This module belongs to the SCRIP library. It is modified to run C within OASIS. C Modifications: C - routine does not read SCRIP grid description files, but gets C arrays from the calling routine C - unit conversion : only from degrees (OASIS unit) to radians C - some allocated array will be freed in the end to allow multiple C calls of SCRIP C - map-methods and restriction-types are written in capital letters C - added bin definition for reduced grid C C Modified by V. Gayler, M&D 20.09.2001 C Modified by D. Declat, CERFACS 27.06.2002 C*********************************************************************** !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! This module reads in and initializes two grids for remapping. ! NOTE: grid1 must be the master grid -- the grid that determines ! which cells participate (e.g. land mask) and the fractional ! area of grid2 cells that participate in the remapping. ! !----------------------------------------------------------------------- ! !
