After reading the projection paragraph 5.6 of CF-1.0 again, I understood
your comment about the NATTOT_year_cf.nc. Adding the coordinates = "lon
lat" flag to the variables made variables longitude and latitude
disappear in the IDV variable listing. But it still doesn't show any
longitude values when showing a variable: The latitude values are all
correct, but for longitude, I allways get 'NA'.
I uploaded the corrected file again:
ftp://emepftp@xxxxxxxxxx/heikok/NATTOT_year_cf.nc
I hope somebody has time to give me a hint where my file is wrong.
Best regards,
Heiko

Your right, the String valued "station" is a extension to CF-1, and not
obvious, though it is not against any CF-1 rule and it should work in a
general CF-1 reader.
Looking at your UnidataObsConvention link, I must admit that this is a
very useful extension to CF-1, and I would like to see it included in
the successor to CF-1. I had some problems adding extensions to CF-1.0,
because in 2.6.1 it says that the Conventions string must be 'CF-1.0',
while the netcdf documentation allows for a comma-separated list of
conventions. I tried some programs (visad, cfchecker.py) and they had
problems when I created files with Conventions = "CF-1.0,GDV".
You leave me puzzled with your comment about "NATTOT_year_cf.nc". This
is a CF-1.0 grid file in polar_stereographic projection I have some
problems with reading into IDV. CF section 5.4 is about Timeseries of
station data. I thought I send you links to two files:
StationObs in CF-1.0: ftp://emepftp@xxxxxxxxxx/heikok/pointData.nc
polar_stereo grid in CF-1.0:
ftp://emepftp@xxxxxxxxxx/heikok/NATTOT_year_cf.nc
