Hi Esben,

Here what I suggest to test your sensitivity.

1- Put your solar flux in W/m^2 in the cloud cover field (<cc>)  in the 
atmospheric forecast file.
2- In the file metro_preprocess_fsint.py, go in the function 
__set_theoretical_flux. It is a big function that compute the solar and 
infra-red fluxes based on the cloud cover. If you look at the end of the 
function, this is where both fluxes are written in the METRo matrix to 
perform the forecast. Put everything you need in comments and manage to 
put exactly what was in the CC field instead of all the computation.
3- Look at the road forecast.

This is a quick and dirty way to perform your test. I did not try it, 
but I think it is a good starting point. I suspect there could be a 
problem in the coupling phase.

If you need to implement it for real in METRo, not only for testing 
purpose, we will manage to do it in a more elegant way.
Keep us inform of your results,

Miguel
