Can we calculate 30 year moving average in cdo by using runmean command?

Hi Jyothi,

the answer is partly yes. Use runmean operator to compute the running mean over a number of timesteps.

If you want to compute a 30 years running mean from 1975-2004 (your file contains the years 1975-2005) then 

cdo runmean,30 infile outfile
Using runmean,31 would compute the 31 years running mean from 1975-2005.
