DESCRIPTION

r.sun.daily is a convenient script for running r.sun for multiple days in a loop. It corresponds to mode 2 (aggregation mode, see r.sun manual page).

Output parameters explanation

There are two basic options:

output series of maps (one for each day): options containing basename in their name
output one map which is a sum of the intermediate maps

You can choose any combination of parameters: e.g. total map of diffuse radiance and series of beam radiance maps. Series of maps are (if flag t is checked) registered to space time raster dataset with relative time and point time (not interval time). For GRASS 6, only timestamp is assigned.

EXAMPLE

r.sun.daily elevation=elevation start_day=30 end_day=40 \
            beam_rad_basename=beam beam_rad=beam_sum nprocs=4 -t
# show information about newly created space time dataset
t.info beam

# show information about newly created beam_sum raster map
r.info beam
