Re: Error in "Run Model"

For diagnosis, could you post your CONTROL, MESSAGE, and SETUP.CFG? If you are running HYSPLIT using a Windows PC and your HYSPLIT is installed at C:\hysplit, the files should be found in C:\hysplit\working. Note SETUP.CFG may not have been created if you didn't change the trajectory setup under the...

Re: HYSPLIT PC – Exit Code 900 with GDAS and RP.gbl Files (Meteorological Input Format Issue)

The NCEP/NCAR reanalysis files (R*.gbl) are already in the ARL format and they are readily usable with HYSPLIT. No conversion is required. To diagnose the issue you reported, could you post SETUP.CFG, CONTROL, and MESSAGE files from your failed trajectory run? ARL has a GDAS one-degree archive. Plea...

Re: tiles for HRRR forecast data
