Secondary inorganic aerosol simulations for Europe with special attention to nitrate
Secondary inorganic aerosol simulations Europe special attention nitrate
2009/2/26
Nitrate is an important component of (secondary inorganic) fine aerosols in Europe. We present a model simulation for the year 1995 in which we account for the formation of secondary inorganic aeroso...
Daily CO2 flux estimates over Europe from continuous atmospheric measurements: 1, inverse methodology
Daily CO2 flux estimates Europe inverse methodology
2009/2/19
This paper presents an inverse method for inferring trace gas fluxes at high temporal (daily) and spatial (model grid) resolution from continuous atmospheric concentration measurements. The method is ...
Characterization of aerosol particle episodes in Finland caused by wildfires in Eastern Europe
aerosol particle episodes Finland wildfires Eastern Europe
2009/2/16
We studied the sources, compositions and size distributions of aerosol particles during long-range transport (LRT) PM2.5 episodes which occurred on 12–15 August, 26–28 August and 5–6 September 2002 i...
The contribution of sulphuric acid to atmospheric particle formation and growth: a comparison between boundary layers in Northern and Central Europe
sulphuric acid atmospheric particle boundary layers Northern and Central Europe
2009/2/12
Atmospheric gaseous sulphuric acid was measured and its influence on particle formation and growth was investigated building on aerosol data. The measurements were part of the EU-project QUEST and too...
High frequency Barium profiles in shells of the Great Scallop Pecten maximus:a methodical long-term and multi-site survey in Western Europe
High frequency Barium profiles Pecten maximus methodical long-term multi-site survey
2010/1/19
Skeletal barium/calcium ([Ba]/[Ca])shell ratios were measured every third daily striae in 39 flat valves of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Euro...
Comparison and evaluation of modelled and GOME measurement derived tropospheric NO2 columns over Western and Eastern Europe
GOME tropospheric NO2 columns Western Eastern Europe
2009/1/23
We present the results of a first comparison of the tropospheric NO2 column amounts derived from the measurements of the Global Ozone Monitoring Experiment (GOME) with the simulated data from a Europ...
The sensitivity of aerosol in Europe to two different emission inventories and temporal distribution of emissions
Europe different emission inventories temporal distribution
2009/1/15
The sensitivity to two different emission inventories, injection altitude and temporal variations of anthropogenic emissions in aerosol modelling is studied, using the two way nested global transport ...
Organic, elemental and inorganic carbon in particulate matter of six urban environments in Europe
Organic elemental inorganic carbon particulate matter Europe
2009/1/14
A series of 7-week sampling campaigns were conducted in urban background sites of six European cities as follows: Duisburg (autumn), Prague (winter), Amsterdam (winter), Helsinki (spring), Barcelona (...
The fate and transport of mercury over Europe is studied using a regional Eulerian transport model. Because gaseous elemental mercury is a long-lived species in the atmosphere, boundary conditions mus...
NO2 Profile retrieval using airborne multi axis UV-visible skylight absorption measurements over central Europe
NO2 Profile UV-visible skylight absorption measurements central Europe
2009/1/13
A recent development in ground-based remote sensing of atmospheric constituents by UV/visible absorption measurements of scattered light is the simultaneous use of several directions with small elevat...
Impact of transatlantic transport episodes on summertime ozone in Europe
transatlantic transport episodes summertime ozone Europe
2009/1/9
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 fr...
Evolution of aerosol optical thickness over Europe during the August 2003 heat wave as seen from CHIMERE model simulations and POLDER data
aerosol optical thickness Europe heat wave CHIMERE model POLDER data
2009/1/8
This study describes the atmospheric aerosol load encountered during the large-scale pollution episode that occurred in August 2003, by means of the aerosol optical thicknesses (AOTs) measured at 865 ...
Episode of unusual high solar ultraviolet radiation over central Europe due to dynamical reduced total ozone in May 2005
Episode of unusual high solar ultraviolet radiation central Europe dynamical reduced total ozone
2009/1/8
In late May 2005 unusual high levels of solar ultraviolet radiation were observed over central Europe. In Northern Germany the measured irradiance of erythemally effective radiation exceeded the clima...
The Spread of Malaria to Southern Europe in Antiquity：New Approaches to Old Problems
Malaria Antiquity Southern Europe
2009/1/6
The discoveries in the late nineteenth century that malaria is caused by protozoan parasites, which are transmitted by mosquitoes, quickly led to intense speculation about its history in antiquity. Th...

Large-scale atmospheric circulation global climate model simulations Central Europe
2009/1/5
The quality of global sea level pressure patterns has been assessed for simulations by 23 coupled climate models. Most models showed high pattern correlations. With respect to the explained spatial va...
