Hi,
I am trying to understand how the solid and liquid precipitation are calculated in ERA5-Land.
I understand that atmospheric forcings in ERA5-Land come from ERA5.
Precipitation in ERA5 come from the IFS model (explicit atmospheric modelling of clouds).
But I have a doubt whether snowfall and rainfall from ERA5 are directly used after interpolation or if total precipitation is interpolated into ERA5-Land’s grid and then rainfall/snowfall is somehow partitioned.
I understand from Muñoz-Sabater et al. (2021) that atmospheric forcings are interpolated but in table A2, “snowfall” is listed as generated field.
Thanks a lot, best regards.
