Re: [ coordinates : lat lon (0) check_for_y_lat_coord: Warning: Data either does not contain a valid latitude coordinate array or doesn't contain one at all...

Sorry, I had a typo. I had you do this:

> media@lat2d=f[:]->lat
> media@lon2d=f[:]->lon

when it should be:

> media@lat2d=f[0]->lat
> media@lon2d=f[0]->lon

Note, and this is important: this assumes that your lat/lon values are the same across all data files. Is this the case?
