Re: working with JJAS time period of different years



Hi Roxy,
Take a look at this FAQ , "Creating Seasonal Masks",
http://www.ferret.noaa.gov/Ferret/FAQ/analysis/seasonal_masking.html

I think it will give you the ideas you need to pick out the range
of months you want.

Hi Ferreters, I have a netcdf file with precipitation
from Jan 1998 to Dec 2002 (pentad values).
I want but to work with the JJAS time period only.
Is there any way I can extract the JJAS time period
of all the years to a new netcdf file?
Or is there another way I can process the JJAS months
together?
I tried with the following method but it is not working:

var=precip[t=01-jun-1998:30-sep-1998]
save/file=precip_jjas.cdf var
var=precip[t=01-jun-1999:30-sep-1999]
save/append/file=precip_jjas.cdf var

Thanks for any help :) Cheers, Roxy
