% This package tries to provide some useful and simple routines to |
| 5 |
|
% compute, visualize and analyze Potential Vorticity from the |
| 6 |
|
% global high resolution (1/8deg) simulation of the MITgcm. |
| 7 |
|
% Routines are as general as possible for extended applications, but |
| 8 |
|
% note that they were developped to focus on the Western Atlantic |
| 9 |
|
% region for the CLIMODE project. |
