A model investigation of tropospheric ozone chemical tendencies in long-range transported pollution plumes

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 ...

A satellite- and model-based assessment of the 2003 Russian fires: Impact on the Arctic region

Isabelle Bey, Sylvia Generoso

In this paper, we address the issues of the representation of boreal fires in a global chemistry and transport model (GEOS-Chem) as well as their contribution to the Arctic aerosol optical thickness and black carbon (BC) deposition, with a focus on the 200 ...

Assimilation of POLDER aerosol optical thickness into the LMDz-INCA model: Implications for the Arctic aerosol burden

Isabelle Bey, Sylvia Generoso

The large spatial and temporal variability of atmospheric aerosol load makes it a challenge to quantify aerosol effect on climate. This study is one of the first attempts to apply data assimilation for the analysis of global aerosol distribution. Aerosol o ...

2006

We analyze present-day and future carbon monoxide (CO) simulations in 26 state-of-the-art atmospheric chemistry models run to study future air quality and climate change. In comparison with near-global satellite observations from the MOPITT instrument and ...

Multimodel ensemble simulations of tropospheric NO2 compared with GOME retrievals for the year 2000

Isabelle Bey, Jérôme Drevet

We present a systematic comparison of tropospheric NO2 from 17 global atmospheric chemistry models with three state-of-the-art retrievals from the Global Ozone Monitoring Experiment (GOME) for the year 2000. The models used constant anthropogenic emissions ...

Long-Range Transport to Europe : Seasonal Variations and Implications for the European Ozone Budget

Isabelle Bey, Marion Auvray

We use a chemical transport model (GEOS-CHEM) to quantify the contribution of long-range transported pollution to the European ozone ({O}{3}) budget for the year 1997. The model reproduces the main features observed over Europe for {O}{3}, carbon monoxid ...

Export of Pollution from Europe: Seasonal and Interannual Variation

Isabelle Bey

Pollution can undergo long-range transport and impact the tropospheric chemistry thousands of kilometers downwind from the source region. Recently, there is interest in the intercontinental transport (ICT) of pollution between the main industrial regions o ...

2003

Elevated mixing ratios of ozone in the lower troposphere are a major summer time air pollution issue in Europe. Photochemical in-situ production is the most important source of ozone in the planetary boundary layer and has been studied extensively. However ...
