Re: loading point-data to idv

Two hours later, reading a lot of the IDV and NetCDF source, I managed to get my file working: I didn't manage to find anywhere the polar_stereographic parameter "straight_vertical_longitude_from_pole" which is defined in CF-1.0 Appendix F.

Using instead "longitude_of_projection_origin" (not mentioned in CF-1.0, but in GDV convention and the source), the file below worked fine. I used the same value for both parameters: Did I misunderstand the "straigth_vertical_longitude_from_pole", or there it simply a bug concerning polar_stereographic in the netcdf CF-1.0 implementation?

Best regards,

Heiko

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,
