I have a data set of CO concentration in the atmosphere for different altitudes according to the longitude and the latitude. I want to plot a 2D surface colormap for CO concentration for latitude and longitude. If I can plot a color map for one altitude I can extend it to a 3D plot later. how can i do that?

Can you show examples? A 2D array is like an image. If you plot that as a surface where the Z value is the gray level and you make a perspective rendering of it, like you get with surf(), then that's kind of like a 2.5D plot. It's not true 3D because there is not a Z value for each x,y pair. A true 3D image would be like a volumetric image like a CT or MRI medical image.

Thank you very much for the reply. I attached a similar image in the comment. Check it out. The colors give you the different concentrations of CO.

I agree with Mohammad. That's why I always check my attachments after I post them to make sure I posted the right thing. Failing an example, about all I can suggest is surf() again. Or since you have lat and long, do you have the Mapping Toolbox? Maybe there are special functions in that - I don't know.
