I have Rcp 4.5 data of precipitation in netcdf file. using arctolbox i can open and get out put for my required area but i can not find units of out put file kindly guide.
Dear Muhammad, I don't know about arctoolbox, but if you are using a linux (or MacOS) environment and have the netCDF library installed, then you can use the simple command-line tool ncdump:
ncdump -h filename.nc
gives out all the header information in the netCDF file filename .nc, including the unit attribute to any variable.
