Hi:<br>
There's an option to the r.univar module that takes a "zones"
raster, and calculates univariate statistics for each zone.
Statistics like mean, max, count, etc are calculated from the input
raster for each category in the zones file. The zones, in your case
would be basins from r.watershed, So you could do:<br>
<tt><br>
r.univar map=temperature zones=basins output=temperature_stats</tt><tt><br>
</tt><br>
I'm not sure this is what you want, but it might get you started...<br>

<div>Hi, </div>
<div>I'm searching for a GRASS command that is able to
"accumulate" a raster following the flow accumulation output
obtained by r.watershed. </div>
<div><br>
</div>
<div>In other words if I have a temperature raster I would like
to accumulate the temperature values following the drainage
direction. The final results would to get the mean of the
uppers stream temperature (so accumulation_temperature /
flowaccumulation). </div>
<div><br>
</div>
<div> r.accumulation input=temperature flowaccumulation=flow
accumulation output=acc_temperature </div>
<div><br>
</div>
<div>It is something that exist? </div>
