Surface photosynthetically active radiation (PAR) in Masfjorden 2010-2011, western Norway

Surface solar irradiance was measured to support a nearby (within 500 m) cabled acoustic observatory (Prihartato et al. 2015, Christiansen et al. 2021, Kaartvedt et al. 2021) to study the behavior of mesopelagic fishes in Masfjorden, western Norway. Surface irradiance in air (PAR, 400 - 700 nm) was recorded every 15 minutes in the period from December 13, 2010 to August 17, 2011.
