Calibrated 2m land RH from ERA5 using a theoretical index of land RH

code_to_generateCalibratedRH.py: Python code to create the calibrated annual and monthly 2m land RH (from ERA5) based on the equation RH_ERA5C = RH_ERA5+(theta_OBS-theta_ERA5)*dRH/dtheta CalibratedERA5_Annual_LandRH_1973_2024.nc: NetCDF contains the annual mean land RH from 1973 to 2024 for the original ERA5, the calibrated ERA5, and the calibrated ERA5 but with climatology adjusted CalibratedERA5_Monthly_LandRH_1973_2024.nc: NetCDF contains the monthly land RH from 1973 to 2024 for the original ERA5, the calibrated ERA5, and the calibrated ERA5 but with climatology adjusted
