separasjonsmodell
Current version: 2025a. New versions will be published as the underlying dataset is
improved. The model gives the vertical separation between Mean sea level and the NN2000
on a regular geographic grid (0.005° × 0.01°), covering the coastal region of mainland
Norway.

The model is made by subtracting HREF2018B from the model for Mean sea level above the ellipsoid.

An estimate of the standard deviation of the model is included as a separate band in the GeoTIFF file. When selecting the bin-format, one gets a separate file with the gridded standard deviation.
