Some RASCAL 4.3 users have experienced this error while attempting to run a saved RASCAL 4.2 case with RASCAL 4.3. The error occurs when the Meteorology button is clicked. The error occurs in Module: frmSTDose_Main; Procedure: ReloadSavedMet.
Reason for Error: This error message occurs because earlier versions of RASCAL don’t contain the 100 mile gridded meteorology which was added in RASCAL 4.3.
Error Resolution: There is no work around for this problem using RASCAL 4.3. The user can continue to do calculations with the loaded 4.2 meteorological datasets but cannot edit the meteorology. The best solution is to update to RASCAL 4.3.2. That version will allow you to access the older met data and generate the needed gridded data.
