Hi Lonneke

x = f->FOO ; (;,:,:) N=>S
printVarSummary(x) ; original order

x = x(:,::-1,:) ; reverse lat CV *and* data array
printVarSummary(x) ; Note the latitude CV

The solution is simple but first a few comments about NCL variables.

printVarSummary is a procedure I use more than any other.

Good luck
