Thanks Hamish,
very useful command that I didn't know but I will try to use it instead of r.mapcalc in some cases.

Cheers

Silvia



Silvia:
- which of these maps created whit the command gives to me the
total radiation for the day? maybe I have to sum some of them but
I don't understand which of them to take into account.
Hamish:
[global] = beam + diffuse + reflected
(add with r.series)
Silvia:
PS: how do you use r.series? I thought to use r.mapcalc

r.series in=beam,diffuse,reflected out=global method=sum


r.mapcalc will work just as well:

r.mapcalc "global = beam + diffuse + reflected"
