ERA5-Land: calculating relative humidity
Dear all,
I'm trying to calculate the RH according to this paper: https://doi.org/10.1029/2022GL099740
In CDO, I am applying the equation as follows (t2m and d2m are already merged into the same file):
cdo expr,'rh=100*(exp((17.67d2m)/(243.5+d2m))/exp((17.67t2m)/(243.5+t2m)))' t2m_d2m_2017.nc rh_2017.nc
The issue is that the RH values are very high throughout the day, consistently above 70%. I'm certain that this does not occur in the area. Perhaps I'm applying the equation incorrectly?
Thank you in advance for your help

Solved!
The data was in Kelvin, but was supposed to be in Celsius for this equation.
Thank you.
