Hi Anna-Marie,
For vector on LLC grid, one needs to rotate the vector to show on
geographic map.
Here are some examples,
https://github.com/gaelforget/gcmfaces/blob/master/gcmfaces_calc/calc_UV_zonmer.m
line 23-24
and
http://wwwcvs.mitgcm.org/viewvc/MITgcm/MITgcm/utils/matlab/cs_grid/latloncap/quikread_llc.m?view=markup&sortby=date
line 31-32
hope it helps,
Hong
