_equalarea_spherical_grid(nlat=30)[source]

Generates a simple spherical equalarea grid that adjust the number of longitude samples to the latitude. This grid is useful to plot vectors on the sphere but not surfaces.

Parameters:

nlat – number of nodes in lat direction. The number of nodes in lon direction is 2*nlat+1 at the equator
