hello all
I have a netcdf file. I want to calculate some attribute with loop for every point separately in same file. what is your suggestion?
I recommend the following module: https://pypi.org/project/netCDF4/
They have a GitHub with documentation and you can open an issue if you have problems that you cannot solve yourself.
thanks for your reply.
Now I want to run this part:
rain1=root.variables[u'tp'][:,i,j]
mxrain=rain1==0
rain2=mxrain-mxrain.mean()
root1.variables[u'tp'][:,i,j]=rain2;
but for the last line, I have this error:
Traceback (most recent call last):
File "", line 1, in
File "netCDF4/_netCDF4.pyx", line 4628, in netCDF4._netCDF4.Variable.__setitem__
File "netCDF4/_netCDF4.pyx", line 4893, in netCDF4._netCDF4.Variable._put
File "netCDF4/_netCDF4.pyx", line 1745, in netCDF4._netCDF4._ensure_nc_success
RuntimeError: NetCDF: Write to read only
I think this error is relate to this point that I can not change a netcdf file?
I should create new netcdf file and define every variable and feature?
