Harbour porpoise habitat suitability layers cover a seascape area of 70,145 km2. Habitat suitability layers are available for the periods: 1997–2004; 2005-2012; 2013-2022 and for both winter (Nov–Apr) and summer (May–Oct). All layers are projected using the EEA reference grid (ETRS89-LAEA Europe, EPSG:3035), have a 1x1 km spatial resolution (cell size) and a spatial extent of 4275000, 4545000, 3415000, 4105000  (xmin, xmax, ymin, ymax). Habitat suitability values (probabilities) range between 1 and 0 with values closer to 1 indicating habitat being highly suitable for harbour porpoises while values closer to 0 indicate habitat that is poorly suitable for harbour porpoises. Location data underlying the habitat suitability models were collected from 111 harbour porpoises tracked over the period 1997–2022 as part of a long-term satellite telemetry monitoring program in Denmark. Location and meta data are freely available at Zenodo (https://doi.org/10.5281/zenodo.13968991). 
Harbour porpoise habitat suitability layers were produced as part of the projects: GES4SEAS (grant agreement no. 101059877) and OBAMA-NEXT (101091642))
