Abstract:

The averages over the duration of the experiment for irradiance values (E; mW/m²/nm) per wavelength (λ) for downwelling E above the ice, upwelling E above the ice, and downwelling E below the ice. Also provided are albedo (0-1 scale), as a ratio of downwelling/upwelling E above the ice, and transmittance (τ), the ratio of downwelling E above the ice and below.
