Measured downwelling plane quantum irradiance (Ed,q) for PAR and 325-nm radiation at the ice surface and modeled scalar quantum irradiance (Eo,q) at different depths in the ice cover on 14 March. The ice surface is indicated as 0 cm, whereas 6 cm is the bottom of granular ice layer, and 37 cm the bottom of ice. Model was run with the measured ice properties (case 1). PAR scale is on the left side and 305- and 325-nm scale on the right side y-axis.
