Re: [ferret_users] monthly averages

Hi Izidine,

It sounds like you want to create a monthly climatology. You can do this
by regridding on the time axis using the @mod transformation. The
climatological_axes command (below) gives you several calendar options to
choose from for your climatology (e.g. month_noleap, month_gregorian,
month_reg).

E.G.:

yes? SET DATA monthly_navy_winds
yes? USE climatological_axes
yes? CANCEL DATA climatological_axes
yes? LET uwnd_climatology = uwnd[GT=month_reg@MOD]



 This is explained in detail in the FAQ here:
