Parameterizations for narrowband and broadband albedo of pure snow, and snow containing mineral dust and black carbon
(Journal of Geophysical Research, 2015-04)
The reduction of snow spectral albedo by black carbon (BC) and mineral dust, both alone and in combination, is computed using radiative-transfer modeling. Broadband albedo is shown for mass fractions covering the full range from pure snow to pure BC and pure dust, and for snow grain radii from 5 μm to 2500 μm, to cover the ...
Measurements of light-absorbing particles in snow across the Arctic, North America, and China: effects on surface albedo
(Journal of Geophysical Research [in revision], 2017)
Using field observation, we perform radiative transfer calculations on snowpacks in the Arctic, China, and North America to quantify the impact of light-absorbing particles (LAPs) on snow albedo and its sensitivity to different factors. For new snow, the regional-averaged albedo reductions caused by all LAPs in the Arctic, ...
Effect of snow grain shape on snow albedo
(Journal of the Atmospheric Sciences, 2016-06)
Radiative transfer models of snow albedo have usually assumed a spherical shape for the snow grains, using Mie theory to compute single-scattering properties. The scattering by more realistic, nonspherical snow grains is less in the forward direction and more to the sides, resulting in a smaller asymmetry factor g (the mean ...
