Abstract Glacier bed topography is crucial for modeling ice mass loss. However, heavily crevassed regions are challenging to survey using conventional methods, leading to data gaps. We establish a passive seismic approach exploiting naturally occurring crevassing events recorded with a dense seismic array to image the ice–bed interface without spatial ...

Global Characterization of Precipitation Peaks in the Seasonal Cycle
Abstract Precipitation seasonality is commonly described using wet and dry periods, but this framework can obscure multiple rainfall maxima within a rainy season. Here we introduce a global framework for identifying the number of precipitation peaks (NPP) during rainy periods from daily precipitation using optimal harmonic seasonal fits and ...

Observational Constraints on Sea Salt Contribution to CCN Over the Southern Ocean
Abstract Earth system models exhibit persistent biases in simulating cloud condensation nuclei (CCN) over the Southern Ocean and Antarctica, largely due to inadequate representation of aerosol sources. Here, we present year‐round (January 2023–February 2024) measurements of aerosol hygroscopicity (HTDMA), particle number size distribution (SMPS), and ...

Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Glacier‐Climate Feedbacks Modulate Last Glacial Maximum Dust Cycle Over the Third Pole
Abstract Geological records indicate only a modest Last Glacial Maximum (LGM) increase in dust deposition over the Third Pole (TP), in contrast to the order‐of‐magnitude rise at high latitudes. Existing climate simulations, which generally prescribe present‐day or no TP glaciers, have struggled to reproduce this muted response.
