Dear Halldór,
I just posted an answer to another Forum post at CARRA East - grid change in 2023 and after - #10 by Andras_Horanyi
I hope, it also answers to your question.
Indeed for the snow depth water equivalent variable there is a change of the “typeOfLevel” variable from “surface” to “heightAboveGround”.
It was an accidental change what we just realised now thanks to your comment.
I apologise for the problem and thank you for informing us.
Best regards
Andras
