To do so, there is only one degree of freedom: radiation. So METRo changes the radiation (both IR and solar) before the forecast time to perform this match and then relax this change after the beginning of road forecast. If you fix the observations of the fluxes, there will be no way to force the road forecast to match the other observations. > Also if you have stations with measured solar flux, it > does not need calibration, so it would be good to use > the calibration part for some other variable, for > example ground heat flux or sensible heat flux.
