DOI: 10.1029/2022gl098102
Abstract: This study employs a fully coupled meteorology‐chemistry‐snow model to investigate the impacts of light‐absorbing particles (LAPs) on snow darkening in the Sierra Nevada. After comprehensive evaluation with spatially and temporally complete satellite retrievals, the model… read more here.

DOI: 10.1109/jstars.2021.3051731
Abstract: We have characterized the snow albedo decay over Hurd Peninsula, Livingston Island, Antarctica, for the period 2000–2016. The snow albedo was obtained from the MOD10A1 product of the spaceborne MODIS sensor. A low-pass filter is… read more here.

DOI: 10.5194/acp-18-11507-2018
Abstract: Abstract. We implement a set of new parameterizations into the widely used Snow, Ice, and Aerosol Radiative (SNICAR) model to account for effects of snow grain shape (spherical vs. nonspherical) and black carbon (BC)–snow mixing state (external… read more here.

DOI: 10.5194/acp-21-6035-2021
Abstract: Abstract. Mineral dust is a major light-absorbing aerosol, which can significantly reduce snow albedo and accelerate snow/glacier melting via wet and dry deposition on snow. In this study, three scenarios of internal mixing of dust… read more here.
