<div>Hi Fanglou,</div>
The file for llc270 basin mask is</div>

also, could you please let me know wethere there is a gcmfaces function transforming eastward and nortwhard componnets to the native ECCO grid, that is has the reverse function to calc_UEVNfromUXVY? I did not find it in the gcmfaces toolbox that I have.<br class="">

You can rotate back from uE/vN to get uX/vY, just reverse of</div>

<div>but uX/vY is on tracer point, still need to figure out how to put onto velocity point.</div>
