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 the geoid on a regular geographic grid (0.005° × 0.01°), covering the coastal region of mainland Norway.

Mean sea level is defined as the average height of the sea surface over a period of 19
years. The period used to define Mean sea level is 1996–2014. It is directly calculated
at the permanent tide gauges where the time series is at least that long. Shorter time
series of water level gives additional estimates of mean sea level. Collocation is used
to combine these observations to a model, and the quality of the model depends on the
length and quality of the observations.

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.
