MATLAB: How to create a temperature colormap over a global map with temperature data from lat/lon

Question

Hi, I am very new to this.

I am looking to make a colormap using temperature data for every lat/lon and plot in on a global map.

For now, I plot my map and the lat/lon but I don't know how to created a temperature map with the data…

I have 3 matrix of 180×360 for the lat, the lon and the temp.

Thank you

Answer 1

imagesc(x,y,C)

where x and y are your lon and lat data and C are your temp data.

It's always a good idea to specify the axes, too.

imagesc(ax,___)
