Do you just want to get the PBL height at a certain location?
You can use one of the utilities that extracts information from the meteorological data.
vmixing or xtrct_stn would work.

era52arl uses the eccodes library to read the grib files.

You may need to contact the administrator of the remote host you are trying to work on.

I'm glad you were able to use the EMITIMES files.
They are designed to be the main way people create complicated emission scenarios.

The pardump files are mostly designed for restarting the model from a previous run and diagnostics.

If you run with multiple levels defined in your concentration grid then the con2asc output will have multiple columns. It looks like you currently have one particle species defined (TEST) and the 05000 indicates that is concentration from ground to 5000m. If you defined another level (maybe 6000m) t...

ARL does not create this dataset.

You may want to contact NCEP/NCAR with any concerns.

You should use ninit=2 because you don’t want to remove particles that were added previously. ----------------------------------------------------------------------------------------- Example. You want to emit 100 g of mass over 1 hour at a constant rate. Set the model time step to 5 minutes (DELT=5...

You may find this technical report by Richard Dare useful. It explains the calculation of the terminal fall velocity of the particles in detail. https://cawcr.gov.au/technical-reports/CTR_079.pdf Here is a relevant section of the HYSPLIT user manual. You may also wish to consult the reference here. ...

Can you attach the MESSAGE file from the HYSPLIT run?
Thank you.

Do the outputs from the dispersion model contain details of the concentrations at different heights, or just one value for the averaged concentration up to a certain height? As I understand from looking at the plots produced by the model it should be the latter, but the former is what I require, th...
