Dear Forum and ARL team, After doing a bit of research, I was unable to find any pre-1948 reanalysis data that could be used with Hysplit. Are you aware of any meteorological dataset that exists or is currently being developed that would cover the time period before NCEP/NCAR? I am particularly inte...

Changing particle density and size during Concentration calculation

Dear Hysplit team, I am working on a problem where particle size and density change with time. While I do not seek to create a new complex chemistry module, I am exploring the possibility to simply readjust the particle size and density at a given time step (switch from distribution 1 to distributio...
