## Read in the model
model = cgeniepy.sample_model()
sst = model.get_var("ocn_sur_temp").isel(time=-1)

## use the Orthographic projection

fig, ax = plt.subplots(subplot_kw={'projection': ccrs.Orthographic()})

## set the color map
sst_plotter= sst.to_GriddedDataVis()
sst_plotter.aes_dict['pcolormesh_kwargs']['cmap'] = plt.cm.inferno
sst_plotter.plot(ax=ax, outline=True)
plt.show()
