Hello,
I am new to NetCDF data and the associated tools. I have downloaded
some files containing 5 years worth of data, and want to create monthly
averages. I am using the ncea utility which is part of the nco suite.
Although I have read through the syntax, I don't think the output files
are quite right. Does anyone have any experience doing this? I used
"ncea -F -d time,1,248,1 tas_MM5I_ccsm_2041010103.nc tas_jan_2041.nc"
and this seemed to work, but to create one for February I tried
"ncea -F -d time,249,472,1 tas_MM5I_ccsm_2041010103.nc tas_feb_2041.nc".
The data is in 3 hour increments, so for January I thought I needed 8 X
31 or the first 248 time slices. Maybe I'm not understanding the data
format correctly.
Any guidance would be appreciated!
Thanks,
Jamie
