thank you it really helps! cheer up to all University of twente students from water ressources department!!

very nice lecture for me!

Is possible to have access to the spreadsheets?

includes the Sensbile Heat (H) the outgoing black body radiation (in this case infrared radiation) or only the the transfer of energy via conduction when the airmolecules collide with the surface? Or in otherway is Rn the net of incoming sunlight minus the outgoing infrared radiation? If so, why would you work with this Rn in an energy balance model? Would it not better to R_full_incoming_sunlight and out R_infrared_surface?

I would also really like to play with the Excel spreadsheet if possible.

how to calculate Ra (ressistance of air in soil arid, not find vegetation) ....

Is there anywhere we can get this leaf energy balance excel? It would be helpful to play with!
