Help in extracting points in NetCDF file

[George]

Hi

I have a netcsf with size 81x49 (longitude=81 and 49=latitude) within i have multiple data of Hs, Tp and other spectral components

I am using python to isolate a specific point only and write the quantities in the format of

TIMESTEP 10 15 5 25 (TIMESTEP A B C D)

but i can't isolate the problem only to one point

does anybody have a code of example for that reason?

thank you

if you use cdo, the following command will work:

cdo sellonlatbox,lon1,lon2,lat1,lat2 input.nc output.nc

if you use cdo, the following command will work:

cdo sellonlatbox,lon1,lon2,lat1,lat2 input.nc output.nc

Thank you rocksea, i am using the latest version of cdo, i indeed isolated the points with CDO when i use the expression "manually" point by point it works, when I although incorporate into a bash looping script, it prompts me that it need more than one inputs.

any idea to why that is?

[rocksea]

could you post your bash script? i have used cdo with bash scripts, and it works fine.

Its a simple script it goes like this

side=North
lon1=8
lat1=61
lon2=6
lon3=4
lon4=2


cdo sellonlatbox,$lon1,$lon2,$lat1,$lat2 input.nc output.nc

and i get this error,

cdo sellonlatbox (Abort): Too few arguments! Need 4 found 3.
