[RegCNET] Which time step to use in monthly file after postprocessing in RegCM4.2

[Kanha Pattnayak]

Thanks Syed
I tried the same suggested by you, still I am getting the same result.
I copied the *average.sh *file from PostProc directory to current output
directory

./average.sh month
India_ATM.2002010100_pressure.nc<http://india_atm.2002010100_pressure.nc/>
 India_ATM.200207.nc <http://india_atm.200207.nc/>

used this command, but got no difference in the result.
With regards
Kanhu
