All, Is there a way to do ranking in Grads? I'm trying to compute return values for a superensemble (>150 members) but I need to be able to rank each member at each grid point. I'm using v2.0.a9.oga.1 little-endian readline printim grib2 netcdf hdf4-sds hdf5 opendap-grids,stn athena geotiff shapefile Robert
