Hi Brian,<br>
<br>
You should be able to use the GrADS function "sum", e.g., 'd
sum(precip,t=1,t=384)'.<br>

<div>Hi,</div>
<div><br>
</div>
I'd like to be able to plot a chart using shading and contours
for a lat long range (rather than single point) which displays
the total accumulated precipitation for a series of time steps
rather than each individual one in the GFS run. For example,
total precipitation for 0 to 384 hours, lat 30 to 60, lon -45
-60.

</div>
<div>The GFS grib2 files don't seem to contain a variable with
this data so I'm guessing it's necessary to sum precipitation
values from each individual file? Any suggestions for the best
way to go about this?</div>
