An assessment of key model parametric uncertainties in projections of Greenland Ice Sheet behavior [PDF]

, 2012
Lack of knowledge about the values of ice sheet model input parameters introduces substantial uncertainty into projections of Greenland Ice Sheet contributions to future sea level rise.

The potential of drone observations to improve air quality predictions by 4D-Var [PDF]

Atmospheric Chemistry and Physics
Vertical 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

Atmospheric ice nuclei in the Eyjafjallajökull volcanic ash plume [PDF]

, 2011
Explosive volcanism affects weather and climate. Primary volcanic ash particles which act as ice nuclei (IN) can modify the phase and properties of cold tropospheric clouds.

A novel conceptual model for Dansgaard–Oeschger event dynamics based on ice-core data [PDF]

Climate of the Past
This 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 ...

Global perspectives on nitrate aerosol dynamics: a comprehensive sensitivity analysis [PDF]

Atmospheric Chemistry and Physics
In 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

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.

Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet: is land-terminating ice thinning at anomalously high rates? [PDF]

, 2008
Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories have been proposed which provide a link between climate

The Response of Ice Sheets to Climate Variability [PDF]

Geophysical Research Letters, 2017
AbstractWest Antarctic Ice Sheet loss is a significant contributor to sea level rise. While the ice loss is thought to be triggered by fluctuations in oceanic heat at the ice shelf bases, ice sheet response to ocean variability remains poorly understood.

Recent trends in melting conditions on the Antarctic Peninsula and their implications for ice-sheet mass balance and sea level [PDF]

, 2006
Long-term records from meteorological stations on the Antarctic Peninsula show strong rising trends in the annual duration of melting conditions. In each case, the trend is statistically significant and represents a major increase in the potential for ...

On the occurrence of annual layers in Dome Fuji ice core early Holocene ice [PDF]

Climate of the Past, 2015
Whereas ice cores from high-accumulation sites in coastal Antarctica clearly demonstrate annual layering, it is debated whether a seasonal signal is also preserved in ice cores from lower-accumulation sites further inland and particularly on the East ...
