HARv2 Data Choice: scld vs scldfra for Cloud Fraction

[M2tHane]

For cloud fraction (N) input data, which variable should I select from HARv2 : scld or scldfra? Thanks.

Please plot the variables and check if they are suitable. I used LWin from HARv2 instead of cloud cover fraction.
I am not sure if there is a variable like TCC (https://codes.ecmwf.int/grib/param-db/164) available in HARv2.
