Hi Ivan,
A simple, quick-and-dirty approach could be:
t.rast.algebra basename=rain5 expression="rain5=rain + rain[-1] + rain[-2] +
rain[-3] + rain[-4] + rain[-5]"
Temporal selection (start_date(rain)...) is probably more elegant...
See:

Subject: [GRASS-user] temporal raster accumulation
Dear GRASS users
I'm a little bit confused about which can be the best module/tool to perform
the following task I have a strd having a daily granularity. It contains total
daily cumulated rainfall.
I would like to create a new strd where, for each day, I have the cumulated
rainfall in the antecedent 5 days
can you kindly suggest which is the best tool (or combination of tools) to
reach this aim?
thank you very much
Ivan
