[GRASS-user] black and white sky albedo MODIS

[Nadine Jeschke]

hello!

Guess my last question was not clear enough...

I´d like to calculate i.evapo.senay and I´m not sure which MODIS albedo values I shall use. Do you use black or white-sky albedo for this calculation? 
Or do I need both, calculated into blue sky albedo before?

hope someone can help! Thanks a lot!
