Dear ferret users,
I am having 40 years model output (1 year) (1967-2007) with 12 months in each file. I would like to make climatology by using these 40 years data, all the these files are in Netcdf, I want the final output with only 12 months , how do I do climatological averages using ferret.

Thank you,

S Aditi

This is very easy:

 ! this will define seasonal and monthly climatological axes
set dat climatological_axes
! have a look at these:
sho axis month_irreg
list t[gt=month_irreg]

! form the climatology:
let vname_cl = vname[gt=month_irreg@mod] ! if "vname" is the name of your variable

! try plotting this to see what it is doing
plot/x=.../y=.../z=... vname
plot/over/x=.../y=.../z=.../t=1-jan-1997:31-dec-2004 vname_cl ! choose the time for your data
