% 1: plot a gcmfaces object face by face (as in Fig. C1) of doi:10.5194/gmd-8-3071-2015). |
| 6 |
|
|
% 2: use convert2array via qwckplot (a quick but crude display option). |
| 7 |
|
|
% 3: use convert2pcol then pcolor (for a display in lat-lon coordinates). |
| 8 |
|
|
% 4: use the m_map_gcmfaces front end to m_map (https://www.eoas.ubc.ca/~rich/map.html). |
| 9 |
|
|
% 5: use gcmfaces_sphere to display fields on a sphere. |
| 10 |
|
|
% 6: use stretched vertical coordinate. |
