In the polar volume data there seems to be an inconsistency in the range scale where some times the rscale is 500 m and sometimes a 1000m (atleast in ES/BAR). Looking at the ppi this does not seem real as often the static objects shift closer and further form the radar, see the plots below where the cutout for the mountains shift. This might impact the quality of vp`s.

The rscale attribute of scan X is copied from the datasetX/where/rscale attribute in the hdf5 polar volume file. As a first sanity check I would verify these attribute values in the raw hdf5 file, e.g. with HDFView
