Raster showing the number of MERIS images that were used to derive KDPAR values for each pixel. Data was collected by the MERIS satellite between 2005 and 2009 and created for use in the 2016 EUSeaMap, but updated in 2018 in order to cover Iceland and the Barents Sea and used in EUSeaMap 2019. Datasets spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. Created by the EMODnet Seabed Habitats consortium using data from the European Space Agency MERIS instrument.

Fraction of surface light reaching the seabed (Fr), values between 0 and 1. Derived from KDPAR and depth rasters (EMODnet bathymetry 100m DTM, 2019) using the following equation; Fr = e^-KDPAR*depth Datasets spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic.

Raster showing the photosynthetic active radiation (PAR) reaching the seabed, values in mol.phot.m^-2.d^-1. Derived by multiplying the fraction of surface light reaching the seabed by the amount of light at the sea surface. Layer created for use in the 2019 EUSeaMap, and updated in 2018 in order to cover Iceland and the Barents Sea. Dataset's spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. Created by the EMODnet Seabed Habitats consortium using data from the European Space Agency MERIS instrument.

Raster showing the average diffuse attenuation coefficient of photosynthetic active radiation (KDPAR) between 2005 and 2009, values in metres^-1. Data was collected by the MERIS satellite and this layer was created for use in the 2019 EUSeaMap. In 2018 the coverage was extended to Iceland and Barents Sea. In 2022 the coverage was extended to the Caspian Sea. Dataset's spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. The spatial resolution of the dataset is around 100m, but that of the original data source is around 250m.

Dataset's spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. Created by ACRI-ST under contract to the EMODnet Seabed Habitats consortium using data from the European Space Agency MERIS instrument. From Salquin et al (2013): "Daily mean PAR (in mol┬Àphotons┬Àd-1┬Àm-2) was evaluated using the algorithm developed by Frouin in 1989 and updated in 2011 for MERIS using Level 1 Reduced Resolution [1km]. The daily fields are averaged temporally over the period 2005 to 2009."
