Re: deseasoned monthly meridional wind

Dear NCL,

Thank you Adam!

If I use the function of ClmMonTLLL then substract the anomalies
via calcMonAnomLLLT
can it be called as deaseasoned monthly data? because as far as i
understand your recommended
trick also do the same

arr_sc(gg,:) = (/ dim_avg_n(arr(gg::12,:),0) /)

thank you for clarification.

AF,
