Initial Request
----------------------------------------------------------------
Hello,
I earlier used pcp_combine -subtract to create files to use in pop_combine sum. However, when I run pcp_combine -sum I get an error that has been proving naughty.
ERROR : sum_data_files() -> Cannot find a file with a valid time of 20190227_060000 and accumulation time of 060000 matching the regular expression ".*”
My command is part of a script:
/Users/bamideleoloruntoba/MET/met-8.0/bin/pcp_combine -sum 20190226_060000 6 20190227_060000 24 ECMWF20190226FC.nc -pcpdir /Volumes/IGNITE/ModelEvaluation/modelbank/ECMWF -field 'name="APCP_Z0"; level="(*,*)";' -v 3
Please find my data attached.
Thanks in advance for your help on this.

Subject: pcp_combine -sum not working.

Bamidele,
I see that you're trying to run the pcp_combine "sum" command to
accumulate
precipitation 4 6-hourly precipitation files into a 24-hour
accumulation.
But the "sum" option isn't working. Thanks for sending you sample
data to
illustrate the situation. Let me suggest 2 different ways you could
fix
this issue.
(1) Instead of using "sum" you could use the "add" option instead,
like
this:
*/Users/bamideleoloruntoba/MET/met-8.0/bin/pcp_combine -add \*
*/Volumes/IGNITE/ModelEvaluation/modelbank/ECMWF/instPRECIP.SOL.06.nc
<http://instPRECIP.SOL.06.nc> 'name="APCP_Z0" ; level="(*,*)";'
\/Volumes/IGNITE/ModelEvaluation/modelbank/ECMWF/instPRECIP.SOL.12.nc
<http://instPRECIP.SOL.12.nc> 'name="APCP_Z0" ; level="(*,*)";'
\/Volumes/IGNITE/ModelEvaluation/modelbank/ECMWF/instPRECIP.SOL.18.nc
<http://instPRECIP.SOL.18.nc> 'name="APCP_Z0" ; level="(*,*)";'
\/Volumes/IGNITE/ModelEvaluation/modelbank/ECMWF/instPRECIP.SOL.24.nc
<http://instPRECIP.SOL.24.nc> 'name="APCP_Z0" ; level="(*,*)";'
\/Volumes/IGNITE/ModelEvaluation/modelbank/ECMWF/instPRECIP.SOL.30.nc
<http://instPRECIP.SOL.30.nc> 'name="APCP_Z0" ; level="(*,*)";' \*
*ECMWF20190226FC_ADD.nc*
The add command simply reads the data you request from each input file
and
adds it up.
(2) If you'd prefer to use the "sum" option, you'll need to modify the
input NetCDF files slightly. Below I've listed the NetCDF header for
these
files. Notice that the accumulation interval is not specified. So
pcp_combine assumes that the accumulation interval is 0:
* float APCP_Z0(lat, lon) ; APCP_Z0:name =
"APCP_Z0"
; APCP_Z0:long_name = "Total precipitation" ;
APCP_Z0:level = "Z0" ; APCP_Z0:units = "kg/m^2"
; APCP_Z0:_FillValue = -9999.f ;
APCP_Z0:init_time = "20190226_000000" ;
APCP_Z0:init_time_ut
= "1551139200" ; APCP_Z0:valid_time = "20190226_180000"
; APCP_Z0:valid_time_ut = "1551204000" ;*
I ran the following commands to add the "accum_time_sec" variable
attribute:
*for cur in `ls -1 *.nc`; do ncatted -a
accum_time_sec,APCP_Z0,o,l,21600
$cur done*
Once those are added, then this sum command works:
*/Users/bamideleoloruntoba/MET/**met-8.0/bin/pcp_combine \*
*-sum 20190226_000000 6 20190227_000000 24 ECMWF20190226FC.nc \*
*-pcpdir /Volumes/IGNITE/ModelEvaluatio**n/modelbank/ECMWF -field
'name="APCP_Z0"; level="(*,*)";' -v 3*
But look at the timestamps closely. The model is initialized at
20190226_000000, not 20190226_060000, like you had listed. This
command
gives you the 24 hours between 20190226_000000 and 20190227_000000.
Thanks,
John
