MATLAB: Getting data values using lat and lon indexes

dimensions mismatchindexing

Hello,

I have 2 column vectors (latitude (2401,1) and longitude (2401,1) and 1 matrix (Cloud top temperature (2401×2401)) extracted from a netcdf file. I would like to know the matrix values corresponding to specific latitude and longitude points. How can I do this?

P.S: I want to do this for 20 netcdf files.

Thank you!

I'd use interp2

Do you simply need a comma? You wrote,

values = data(lon_indices lat_indices);

Perhaps it should be

values = data(lon_indices,lat_indices);

MATLAB: How can plot precipitation data with latitude longitude information? I have matrix of precipitation over the time,latitude and longitude all are in 470160140 dimensions.

Let lon, lat, P be your matrices of size 470*160*140.

[m,n,p] = size(P) ;
for i = 1:p
    pcolor(lon(:,:,i),lat(:,:,i),P(:,:,i)) ; 
    shading interp 
    colorbar
    drawnow 
end

You can also use surf, contour, countourf.
