how to obatin running data

Post by yuan »

I have successfully run the concentration model. Is there a way to obtain the resulting data (e.g. diffusion duration and particle arrival height) in TXT format instead of displaying the figure?

The concentration output files are binary files and their format is described here.

HYSPLIT distribution comes with a con2asc utility which will convert these files into ascii text files.
There are some other utilities such ash xtrct_stn and con2stn which will extract time series of concentrations or concentrations at specific locations.

There is a pretty active HYSPLIT community that uses R. So there is quite a lot of R code available for running HYSPLIT and reading output files.
splitR is one popular package.

There is also some python code which will read the concentrations files into an xarray DataSet.
