[gradsusr] Temporal correlation map at each grid point

[rahmat hidayat]

Hi Saeed,

Thanks a lot for your attached script. The scripts is for correlation
coeficient betwen single time series (precipitation) and time series of wind
and slp fields (x-y domain).

My purpose is similar but a litle bit defferent, that is time varying of
correlation coeficient between 2 variables field (x-y domain). Say I
have Observed precipition field (Obs)  and model precipitation field
(Mod) and I would like to calculate time varying correlation coeficient at
each grid point (point-by-point temporal correlation) betwen these two
fields. For example, calculating tcorr between time series of Obs and time
series of Mod  at grid 1, and the same way also for grid 2, grid 3 and so
on. So finally we can produce correlation coeficient map/
point-by-point correlation coeficeint.

Do have any idea?

thank you in advance.

regards,
Rahmat
