Goal: Learn how to write data in CDAT.

Writing data in CDAT is very easy, just define a variable you want to save to a file, open file to write and enter command to write data. The output file will be a NetCDF file with the variable data and it's annotation.

import cdms 
f = cdms.open('sample.nc') 
u =f('u')    # read data from an input file
f.close()
 
# write the variable u to a new file 
g = cdms.open('sample2.nc','w') 
# The 'w' option in the above command means 
# the file is opened write-enabled and if the 
# file name did not exist, a new file was created.
g.write(u) 
g.close()  # close the new file
