Conversion programs • Re: ERA5 data for HYSPLIT

Hi Tim,

In order to convert the ERA5 data to the arl format you need 3 files:
- A dataset from "ERA5 hourly data on pressure levels from 1940 to present". Stating it simply: this is the 3D data.
- A dataset from "ERA5 hourly data on single levels from 1940 to present". This is the surface data which you currently miss.
- A geopotential dataset. This must be downloaded from the "ERA5 hourly data on single levels from 1940 to present" dataset individually too.

Together, these three files can be converted into one .arl file. You can do this in the GUI.

Kind regards,
Jasper
