Conversion programs • ERA5 data for HYSPLIT

Hello,
Thanks for providing this great tool.
I am trying to use ERA5 data to drive HYSPLIT simulations. I have downloaded a day's worth (1 Jan 2021) of hourly ERA5 data (https://cds.climate.copernicus.eu/datas ... b=overview) for all variables and all pressure levels. I have successfully compiled era52arl.f. I'm confused by its requirement of a "surface level file" for input data.

What ERA5 data product provides the required surface data?

Any help much appreciated.

Thanks,
Tim
