Description

This PR adds a file that has dust model fields in it from both the CLASSIC/UM model and the UKCA/GLOMAP model used by LFRic. This file is to be used for some vader ctests for transforming from CLASSIC (UM) to UKCA/GLOMAP (LFRic). The file was created separately using the lfricjedi_write_gauss_state ctest, taking inputs of the 4 LFRIC dust fields, first deriving the 2 UM fields and then rederiving the 4 LFRic dust fields from them. Finally then regridding. (Note that the 2 step transformation process was needed because the lfric2um and um2lfric dust transforms are not reversable.)

Checklist

I have checked that the fields in this file look reasonable and have checked that the dust vader ctests work using this file.

Do you think its worth adding some information in a README.md? If a readme does not exist in this directory perhaps it should. What do you think @svahl991
