Problems with polar-stereographic 3d files

Hi,

I've been using IDV for a while to display 2d fields in a polar-stereographic grid (CF convention). Now I tried to see a 3d field with sigma levels. Though the projection parameters are the same, when looking at a plan-view of a single layer, idv reverts to its default projection instead of my polar-stereographic view.

When I try to make a vertical cross-section, I cannot see any data. The altitude display shows always a 'Distance along transect' scale from -0.4km .. 0.4 km and no altitude scale at all (autoscale y axis). The location coordinates of the cross-section are updated correctly.

This looks all like a problem with my projection in the 3d fields, but I couldn't find any mistakes. Maybe somebody else can look at it? The file can be downloaded at ftp://ftp.met.no/pub/emep/heikok/Base_hour.nc

Best regards,

Heiko
