Hi Stephanie, Don is correct about remote Grib file reading. Your test confirms it since you can download the file and it reads correctly. But, can I get a copy of the file so I can do some test to see if there are any other problems. I tried to download the file myself but the url http://cipsstandby/cips/cal/catalogue/grib.grb said the address wasn't found. Thanks, RObb...
