Abrupt CO2 release to the atmosphere under glacia and early interglacial climate conditions

Gas is trapped in polar ice at depths of ∼50-120 m and is therefore significantly younger than the ice in which it is embedded. The age difference is not well constrained for slowly accumulating ice on the East Antarctic Plateau, introducing a significant ...

Synoptic conditions and atmospheric moisture pathways associated with virga and precipitation over coastal Adelie Land in Antarctica

Alexis Berne, Etienne Gabriel Henri Vignon, Nicolas Jean François Jullien

Precipitation falling over the coastal regions of Antarctica often experiences low-level sublimation within the dry katabatic layer. The amount of water that reaches the ground surface is thereby considerably reduced. This paper investigates the synoptic c ...

On the fine vertical structure of the low troposphere over the coastal margins of East Antarctica

Alexis Berne, Etienne Gabriel Henri Vignon

In this study, 8 years of high-resolution radiosonde data at nine Antarctic stations are analysed to provide the first large-scale characterization of the fine vertical structure of the low troposphere up to 3 km altitude over the coastal margins of East A ...

The vertical structure of precipitation at two stations in East Antarctica derived from micro rain radars

Alexis Berne, Jacopo Grazioli

Precipitation over Antarctica is the main term in the surface mass balance of the Antarctic ice sheet, which is crucial for the future evolution of the sea level worldwide. Precipitation, however, remains poorly documented and understood mainly because of ...

Detailed simulations of spatial snow accumulation patterns and near surface snow properties in Dronning Maud Land, East Antarctica

Michael Lehning, Wolf Hendrik Huwald, Nander Wever

Snow accumulation is an important component of Antarctic Ice Sheet Surface Mass Balance (SMB). However, accumulation rates are generally low, and snow redistribution by wind is not only common, but also of the same order of magnitude as precipitation. This ...

Timescales of the Climate Record in the South Polar Ice Cap of Mars

Stepan Tulyakov, Nicolas Thomas

The South Polar Layered Deposits (SPLD) are the largest water ice reservoirs on Mars. Their accumulation is believed to result from climate oscillations that drive the movement of ice and dust on the surface. The High-Resolution Imaging Science Experiment ...

Trends of surface maximum ozone concentrations in Switzerland based on meteorological adjustment for the period 1990-2014

Satoshi Takahama, Eirini Boleti, Christoph Hueglin

We investigate the temporal trends of peak ozone in Switzerland for the 1990-2014 time period. The meteorological conditions have a large influence on ozone formation and drive a large part of the variability in ozone observations. Therefore, the influence ...

Precipitation at Dumont d'Urville, Adelie Land, East Antarctica: the APRES3 field campaigns dataset

Alexis Berne, Jacopo Grazioli, Christophe Praz

Compared to the other continents and lands, Antarctica suffers from a severe shortage of in situ observations of precipitation. APRES3 (Antarctic Precipitation, Remote Sensing from Surface and Space) is a program dedicated to improving the observation of A ...
