Dear Ferret Users,

I am using FERRET v6.95 on Linux.

1) How to calculate spatial correlation between point observation at one location and model simulated data over some particular region. For example, observation is at only one location 18N, 72 E and model is at 0.5x0.5 grid. So how to calculate correlation between every grid of model (over the region 50:100E, 10S:40N) and this point observation at 18N, 72 E. And then save output fine in cdf format. We have extracted model data as same day as observation.

2) Its similar to above but, how to calculate spatial correlation between two model simulated data (i.e. grid to grid correlation over the region50:100E, 10S:40N). One model has 0.25x0.25 and other is has 0.5x0.5 horizontal resolution.

Great Thanks,

Best regards,

Yogesh
