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

The height difference from Mean sea level and LAT is based on harmonic analysis of time
series from tide gauges, which combined with estimated values form a dataset used in a
collocation to calculate the model. While Mean sea level varies little with distance,
the tides can change significantly over short distances, e.g. through narrow sounds, and
in such areas the model may be less accurate. The quality of the model depends on
location and available water level measurements in the area.

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.
