[ferret_users] anomaly and climatology

[DELCLAUX Francois <francois.delclaux@xxxxxxxxxxxxxxxxxxx>]

Hi Ferret users,

I have a grid(x,y) monthly time-series data of an anomaly variable, say  
: pa  (n values)
I have a grid(x,y)  monthly climatological variable, say pc (12 values)

Now I would like to build a time series data of the real variable p, on 
the same time-axis as pa
such as : (in the following, the index corresponds to L index according 
to ferret  definition)

p(1) = pa(1) + pc(1)
p(2) = pa(2) + pc(2)
p(12) = pa(12) + pc(12)
....
p(13) = pa(13) + pc(1)
p(14) = pa(14) + pc(2)
....
p(n) = pa(n) + pc(12)

What is the best way for doing that operation ?

Thanks a lot for answers.

Sincerely yours.
