The performance of a set of atmospheric models and meteorological reanalyses in the representation of precipitation days in Antarctica is assessed using ground-based observations such as a precipitation gauge and a Micro Rain Radar during the Year Of Polar ...
In the present study, we present the aerosol optical properties and radiative forcing (RF) of the tropospheric and stratospheric smoke layers, observed by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, during the ...
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 ...
Snowfall in Antarctica is a key term of the ice sheet mass budget that influences the sea level at global scale. Over the continental margins, persistent katabatic winds blow all year long and supply the lower troposphere with unsaturated air. We show that ...
The fourth report of the Intergovernmental Panel of Climate Change (IPCC) unambiguously indicates that the climate is changing. Climate change is induced by changes in atmospheric abundances of greenhouse gases and aerosols, solar radiation and land surfac ...
Tropospheric ozone is a climate relevant greenhouse gas, as well as an atmospheric pollutant. Its abundance in the troposphere is mainly governed by the influx of stratospheric air masses and the photochemical production due to anthropogenic and biogenic o ...
This paper reports on the transport of ozone O3 and related species over the North Atlantic ocean and its impact on Europe. Measurements of nitrogen dioxide (NO2)and carbon monoxide (CO) columns from the GOME and MOPITT satellite instrument ...
The Raman Lidar for Meteorological Observations (RALMO) was installed at the MeteoSwiss Regional Center of Payerne, Switzerland, in summer 2008. One of its aims is to provide continuous vertical profiles of tropospheric water vapor during day and night at ...
We use the GEOS-Chem model to interpret long-term measurements of tropospheric O3 and CO and to investigate the factors that contribute to their interannual variation (IAV) during the period from 1987 to 2005 with a focus on the northern mid-latitu ...
The impact of continental outflow on the ozone chemical tendencies (i.e., production and loss rates) is quantified in the North Atlantic and northwest Pacific regions using the GEOS-Chem and the MOZECH global models of chemistry and transport. The ozone te ...
