Sorry again,
I forgot to ask you about the Linke turbidity atmospheric coefficient. Is it
included into the script? and which is the value used? (3.0 ?)
Thanks again,
Salvatore

Depending on your terrain that can
Hi Hamish,
now I can't verify in which way the sun map made with arcGIS was done (albedo,
atmospheric turbidity…) maybe the differences depend on terrain shadow effect
that I have not considered in grass map.
If I want to add this effect to your script for global radiation, how can I do?
And mo

how much different? just by a few percent or wildly different
Hi,
thanks for the script, it works. I want to be sure that the result is the
global radiation map expressed in W/m2/yr (or it is W/pixel/yr?). I compare it
with ones made with ArcGis and the values are differents.
Another question…the albedo effect is excluded?
Thanks
Salvatore

Dear Markus,
I try to use rsun_crop.sh, but I received same error message, where I make a
mistake?
Computing radiation for day 075...
Mode 2: integrated daily irradiation for a given day of the year

You can find a ascript here:

-> rsun_crop.sh

Hi,
I want to generate a cumulative annual map for solar radiation (W/m2/yr). It is
possible with r.sun? There is a script to do this?
Thanks,
