Goal: Learn how to concatenate NetCDF files in CDAT.

import cdms

path=sys.prefix+'/sample_data/'

files = [ path+'u_2000.nc',
          path+'u_2001.nc',
          path+'u_2002.nc',
         ]

# First let's open the output file for writing (and possibly erase existing file)
fout=cdms.open('u_concatenated.nc','w')

for file in files:
    f=cdms.open(file)
    u=f('u')
    f.close()
    fout.write(u)

fout.close()
