Re: warning:ContourPlotInitialize: no valid values in scalar field; ContourPlot not possible:[errno=1101]

This is the same problem as before: the media array has no lat/lon
information associated with it.

Your variable has a "coordinates" attribute, which tells you what the
lat/lon arrays should be called on the file. So, you need to do the
lat2d/lon2d setting I showed you before:

t@lat2d = f->lat
t@lon2d= f->lon
