Hello,

I have tried to compare Mean Radiant Tempaerature (MRT) fields from Mars catalogue and the result of the thermofeel method calculate\_mean\_radiant\_temperature, based on fluxes fields also extracted from Mars (same run, same step ranges, same area, same grid). After decumulating fluxes fields, and solar zenithal angle (with earth kit), the resulting MRT differs quite significantly with “native” MRT from Mars (much more than between the two step fields of a MRT).

Do you have explanation about these differences (averages fluxes, etc) ?
