[ncl-talk] Coordinate variables must be the same dimension as their dimension

[alesall]

Hello Amadou,

it looks like something in the script is preventing the appropriate lon/lat to be paired to u and v. 
u has its own lon/lat already, so where are you reading the other lon/lat from? [and do you need to?]

best, alessandra
