Global map based on data from a 3D matrix

Hello,

I have a 3D data file with logitude, latitude, temperature. I need to plot the temperature on a global map.

size(lon)=360 x 1 size(lat)=180 x 1 size(temp) = 360 x 180 x 12

I got the map as below but confused in mapping the "temp" correctly.

worldmap('world')

load coastlines

plotm(coastlat,coastlon)

Please help me with this.

You have the problem that you have 2D data for each of 12 months. You can only plot data for one month at a time

contourm(lat, lon, temp(:,:,MonthNumber))

The exception to this would be that in theory you could choose to "hold on" and plot all of the months on top of each other, using a different contour line color each time.

cmap = colormap(parula(12));

hold on
for MonthNumber = 1 : 12
    contourm(lat, lon, temp(:,:,MonthNumber), 'EdgeColor', cmap(MonthNumber));
end
hold off
