Photosynthetically available radiation (PAR) from Kangerlussuaq, Greenland
This dataset consists of downwelling and upwelling under ice PAR (photosynthetically available radiation; 400-700 nm wave band) and spectral irradiance data collected in March 2013 on the ice in Kangerlussuaq, west Greenland. Under ice downwelling PAR and spectral irradiance in this area are well kn...
