[ferret_users] Spatial Correlation;

[Karnan C <karnanc6@xxxxxxxxx>]

Dear ferret users,

I tried to correlate chl data with sea surface height, for that I set
these two data sets in a common grid.

I followed the scripts mentioned in the page
"http://ferret.pmel.noaa.gov/Ferret/faq/correlations-and-variances";.
This method is working well for coads_climatology data.

use data coads_clim.nc
let p=sst
let q=airt
go variance
fill correl

But, not for my data. I can't understand the reason.


use data relate.nc
let p=ssh
let q=chl
go variance
fill correl

(output shows 'no valid data')
The sample data files attached here.
Kindly help me.
Thanks.
