Examples


In this example, we extract data from the “Temperature” field from the region defined in EOS_GD_DEFBOXREGION. The size of the subsetted region for the field is given by the EOS_GD_REGIONINFO routine.

status = EOS_GD_EXTRACTREGION(EOS_GD_id, regionID, $
   "Temperature", datbuf32)

Syntax


Result = EOS_GD_EXTRACTREGION(gridID, regionID, fieldname, buffer)

Return Value
