[Met_help] [rt.rap.ucar.edu #80002] History for accumulating from multiple levels at once

[John Halley Gotway via RT]

  Initial Request
----------------------------------------------------------------

Dear MET Help staff,

My total precip is spread along the time dimension in a NetCDF file and 
I'm trying to add multiple levels of the it using pcp_combine. It is 
possible to specify multiple levels for the in_accum1 argument?

Like, pcp_combine -add input.nc 'name="prec"; level="(0:3,*,*)";' 
output.nc or similar

or I have to do

pcp_combine -add

     input.nc 'name="prec"; level="(0,*,*)";' input.nc 'name="prec"; 
level="(1,*,*)";' input.nc 'name="prec"; level="(2,*,*)";' input.nc 
'name="prec"; level="(3,*,*)";' output.nc

Thank you

Best regards

JR Garcia,

Unfortunately no, pcp_combine is not set up to support a range of
values
for each dimension.  You're stuck with the latter option, specifying
each
field separately.

If you need to do this over 90 fields (as you mentioned in a different
met_help ticket), you could either build one very log command line, or
do
it in a loop... loop 1 to 90 and accumulate the values from one
timestep at
a time.

Hope that helps clarify.

Thanks,
John Halley Gotway
