plotting the CAM-SE grid

Hi, I wanted to plot the CAM-SE grid, but I don't get a grid of evenly square-sh cells, but rather a mix of squares and rectangular cells. I've attached a plot of the topography with red gridlines.

Is this how the grid is suppossed to look?

Could I be plotting it incorrectly perhaps?


Answer from Peter Hjort Lauritzen

"Yes the plot is correct. You are plotting the grid in which a control volume around each quadrature grid point has been defined. The quadrature grid is not equally spaced and hence you get a non-equal-area grid. If you were to only plot the elements (not the quadrature grid) then you would get a cubed-sphere equiangular grid where the control volumes are approximately the same size."
