[gradsusr] Accumulated Precip issues

[Mike Manning]

Hi all,

 

There are several models which provide GRIB2 data with say 3 hourly until x
amount of hours and then 6 hourly until the end of that run.  Some models
even have a tertiary time step where they run hourly, 3 hourly and then 6
hourly data..

 

At the moment for templating, I'm creating a control file for each series
however this doesn't seem ideal for accumulated precip.  EG I can use
sum(apcpsfc, t=1, t=72) for a model that uses hourly from 1-72 hours, but
what would I do for a model that then goes 3 hourly from 72-144 hours for
accumulated precip? How would I get the entire 1-144 hours of accumulated
precip totals? Is there a better way of templating the data so it's all
combined or does it need to be kept separate because I'm dealing with
different time series? I can't seem to find any way to tally together the
accumulated precip data once the time series changes from hourly to 3 hourly
(and again for models that have 3 time series such as UKMO)

 

Cheers, Mike
