Hello,

I use this to discriminate between rain and snow.

....
'onlysnow=maskout(precip,273-t2m)'
'onlyrain=maskout(precip,t2m-273)'
'rain=const(onlyrain,0,-u)'
'snow=const(onlysnow,0,-u)'
....

and in your case I think the following might work::

**** humidity if T < 10, Temperature if T > 10 ****
'variable1=maskout(t2m,283-t2m)'
'variable2=maskout(rh,t2m-283)'
'var1=const(variable1,0,-u)'
'var2=const(variable2,0,-u)'
'total=var1+var2'


Best regards

Wolfgang Linder
