Dear Yi Wang,

I'm not sure how you tried reordering your longitude values, but we
have nice function called "lonFlip" for doing this. This function will
reorder both your longitude coordinate array and the data
appropriately.

If your data is 2-dimensinal and the rightmost dimension is the
longitude dimension, then this function could be useful for
you. Please see:

for more information. You will need to load the contributed.ncl script
to have access to this function:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
