Merging era5_land and era5_single netcdf files

[abdulrehman565]

I am taking the pressure, kin, kout from era5_single product from the following link
https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels?tab=overview

and I am taking precipitation and temperature data from era5_land product
https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-land?tab=overview

The precipitation data worked but it gave an error during the calculation of temp_pet_fn. (attached below)
Is there a way to merge era5_land and era5_single file so that it works correctly?

For forcing, precipitation and temperature can come from a different data source.
To compute pet, all required variables should come from the same single data source {"temp", "press" or "press_msl", "kin", "kout"}. Else you have some pre-processing to do on your own before using hydromt to compute PET but I would really recommend using the same data source
