[GRASS-user] r.sun and tree-grass ecocystem model

[Dimos]

Hello All,

Grass newbie here! It would be great if you can give
me some hints and ideas on past work and code for the
question below: 

I would like to model solar radiation at an
agricultural environment, specifically at a tree
orchard, and estimate diffused and direct radiation at
the shadowed and non-shadoawed areas of trees,
depending on sun position.

The input would be spatial position and dimensional
properties of trees and plants. Then, I would need to
model shadow and radiation based on sun position for a
given date time.

I think r.sun, h.parameters, h.evapo, h.interception
would be some of the commants used.

Best, Dimos
