Oh, duh! I had this:

> s = Size(array, /Dimensions)
> lats = Scale_Vector(Findgen(s[0]), 0, 90)
> lons = Scale_Vector(Findgen(s[1]), 270, 360)
> cgContour, array, lons, lats

And, of course, it should have been this:

s = Size(array, /Dimensions)
lons = Scale_Vector(Findgen(s[0]), 270, 360)
lats = Scale_Vector(Findgen(s[1]), 0, 90) - 90
cgContour, array, lons, lats

Really bad day today. It all started when I misspelled "aerosol" as
"areosol". But, it's a long story. :-(

Cheers,

David
