WebMar 28, 2024 · From the fact that the names of the variables you're multiplying by 180/pi in your meshgrid calls imply that those variables are in radians (meaning you're gridding degree data) I don't think you calling sph2cart with angles in radians. You're trying to convert the gridded degree data.

Then you plot them with surf(). When using sph2cart(), note that the elevation angle is defined differently in sph2cart() than the polar angle theta in Matlab's legendre(). That is why, in the example cited above, they use pi/2-theta: new glasgow red cross
