Extracting whole layer as csv
Added by Lewis Dorling almost 3 years ago
Hi there,
I have a netcdf file that has one layer in it and I would like to extract all of the data for every grid point into a csv so I end up having for every grid point a lon, lat , value and have it stored in one csv file. I have only read about extracting timeseries from individual grid points so far so was wondering if it was possible to do this. I assume it is some combination of outputtab and remappn but I am unable to figure it out.
Cheers
Lewis

Hi Lewis,
it is easy to write the lat, lon, and values of data on a horizontal grid to a CSV file. See https://code.mpimet.mpg.de/projects/cdo/embedded/cdo.pdf#subsection.2.14.6
For example:
cdo -outputtab,date,time,lat,lon,value -selname,tsurf,precip infile.nc > outfile.csv
outfile.csv:
# date time lat lon name value 2001-01-01 00:00:00 88.5722 -180 tsurf 242.3883 2001-01-01 00:00:00 88.5722 -178.125 tsurf 242.3512 2001-01-01 00:00:00 88.5722 -176.25 tsurf 242.234 2001-01-01 00:00:00 88.5722 -174.375 tsurf 242.2379 2001-01-01 00:00:00 88.5722 -172.5 tsurf 242.2672 ... 2001-01-01 00:00:00 -88.5722 176.25 tsurf 236.0914 2001-01-01 00:00:00 -88.5722 178.125 tsurf 236.0719 2001-01-01 00:00:00 88.5722 -180 precip 1.843902e-06 2001-01-01 00:00:00 88.5722 -178.125 precip 1.843902e-06 2001-01-01 00:00:00 88.5722 -176.25 precip 1.843902e-06 2001-01-01 00:00:00 88.5722 -174.375 precip 1.844019e-06 ... 2001-01-10 18:00:00 -88.5722 176.25 precip 9.212643e-06 2001-01-10 18:00:00 -88.5722 178.125 precip 9.223586e-06
