Correlation between matrices with different dimensions (spatial resolution)

Hello,

I have two matrices, temp with dimensions 609x881x372 and slp (sea level pressure) with dimensions 241x81x372.

This variables are monthly mean extracted in the same area (arctic ocean) but with a different spatial resultion.

Is it possible to calculate the correlation at each grid points and then plot them?

Thank you :)

Here I attached the two variables that I extracted for the first time step.

Define the "correlation at a grid point"

[Carlotta Dentico]

I mean the correlation at every point in the map

A correlation calculation requires some sort of statistical average,

What are you averaging over in your case?

You can use imresize3 to resampe the arrays at a common resolution.
