Can I make a surface or colormap with latitude, longitude, and concentration using MATLAB? (photo example)

4 views (last 30 days)
Hi there,
I am assisting in some research based on climate model outputs. I have datasets for various values (e.g. CO2 concentration, water vapor concentration) at various latitude and longitudes (of systematic intervals). I also need to create similar colored maps for latitude vs. altitude. [Picture examples are linked to below.] I basically have the datasets in txt files that are about a 20 x 20 matrix based on the lat/long intervals.
Can I create these graphs using MATLAB? How should I go about doing this?
Thank you so much!
Aaron

Have you looked at the pcolor function? Here's an example:
[x,y,z] = peaks;
pcolor(x,y,z);
Based on your example pictures, you may also want to do this:
shading interp
The "vertical" picture also appears to have some contour lines:
[x,y,z] = peaks;
pcolor(x,y,z);
shading interp
hold on
contour(x,y,z, [-2, 2], 'EdgeColor', 'k');
Other commands you might want to look at: clabel, colorbar.

I was just using the PEAKS function to generate sample data. Don't use that in your actual plot. Substitute your own data for x, y, and z.
