- How do I change a GRIB2 formatted file to a ARL type formatted file?
- Is there a program that will do this?
- Should I change from GRIB2 to GRIB1 back to ARL?

Thanks, all.

Please try adding more particles and see if your results are sensitive to that parameter. I calculated the 'numpar' parameter from -2,500 to -5,000 and 10,000. 'Maxpar' parameter were changed from 300,000 to 600,000, but the same thing happened. I found that this phenomenon is limited to ground lev...

When calculating the concentration, the concentration is fragmented in a specific area. Do you have any idea why this is happening? I used GDAS half degree data at NOAA archived.

thank you,
