Remote Sensing Sediment–Albedo Feedbacks Affecting Ice Thickness on Taylor Valley Lakes, Antarctica
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The McMurdo Dry Valleys are the largest unglaciated region in Antarctica and home to perennially frozen lakes. Thirty years of ice thickness measurements reveal meter‐scale fluctuations over decadal time scales. In this paper, we hypothesize that changing surface sediment dynamics alter ice albedo, changing the heat balance and thickness of ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract Mixed‐phase clouds modulate the water and energy cycles of high‐latitude regions, yet their liquid‐ice phase partitioning has long been poorly simulated in climate models. Here, simulations of Arctic mixed‐phase clouds by the Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM) are assessed against large‐eddy simulations, satellite data, and ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract We present a method for retrieving cloud optical depth that applies 3D radiative transfer to utilize the combination of polarimetry and multi‐spectral imagery that is newly available from satellite missions such as the Plankton, Aerosol, Cloud, Ocean, Ecosystem (PACE) Mission. Due to the approximate spectral invariance of scattering by clouds,
