Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]
, 2012 We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

Arctic Freshwater Ice and Its Climatic Role [PDF]
AMBIO, 2011 Freshwater ice dominates the Arctic terrestrial environment and significantly impacts bio-physical and socio-economic systems. Unlike other major cryospheric components that either blanket large expanses (e.g., snow, permafrost, sea ice) or are concentrated in specific locations, lake and river ice are interwoven into the terrestrial landscape through ...

The potential of drone observations to improve air quality predictions by 4D-Var [PDF]
Atmospheric Chemistry and PhysicsVertical profiles of atmospheric pollutants, acquired by uncrewed aerial vehicles (UAVs, known as drones), represent a new type of observation that can help to fill the existing observation gap in the planetary boundary layer (PBL). This article presents

A multi-ice-core, annual-layer-counted Greenland ice-core chronology for the last 3800 years: GICC21 [PDF]
Climate of the Past, 2022 Ice-core timescales are vital for the understanding of past climate; hence they should be updated whenever significant amounts of new data become available.

A novel conceptual model for Dansgaard–Oeschger event dynamics based on ice-core data [PDF]
Climate of the PastThis study introduces a novel dynamical systems model designed to capture the highly non-periodic nature of Dansgaard–Oeschger (DO) events. Such events are difficult to model adequately due to their variable durations (some lasting around 1 century ...

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]
, 2004 Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

Global perspectives on nitrate aerosol dynamics: a comprehensive sensitivity analysis [PDF]
Atmospheric Chemistry and PhysicsIn recent years, nitrate aerosols have become a dominant component of atmospheric composition, surpassing sulfate in both concentration and climatic impact. However, accurately simulating nitrate remains a major challenge for global models due to complex

Rain driven by receding ice sheets as a cause of past climate change [PDF]
, 2009 The Younger Dryas cold period, which interrupted the transition from the last ice age to modern conditions in Greenland, is one of the most dramatic incidents of abrupt climate change reconstructed from paleoclimate proxy records. Changes in the Atlantic

Kinetics of the reactions of OH with CO, NO, and NO2 and of HO2 with NO2 in air at 1 atm pressure, room temperature, and tropospheric water vapour concentrations [PDF]
Atmospheric Chemistry and PhysicsThe termolecular reactions of hydroxyl radicals (OH) with carbon monoxide (CO), nitric oxide (NO), and nitrogen dioxides (NO2) and the termolecular reaction of hydroperoxy radicals (HO2) with NO2 greatly impact the atmospheric oxidation efficiency.
