[ncl-talk] check_for_y_lat_coord: Warning:

[Mary Haley]

Noelia,

When you continue to have problems with a script, it helps to include any
new error messages you are getting.

Also, your "printVarSummary" of "oz" seems to indicate that you have
coordinate arrays and the appropriate metadata, so I'm not sure why you are
reattaching all of it.

Please look at your data right before you plot it, and not right before you
start adding metadata to it. Also, look at your lat/lon arrays to make sure
they look okay.

To look at your data more thoroughly, add these three lines right before
you call gsn_csm_contour_plot:

printVarSummary(oz)
printVarSummary(oz&lat)
printVarSummary(oz&lon)

Make sure the "units" for the lat/lon arrays are correct, and that "oz" has
all the correct coordinate information attached.
