The simulation of the Antarctic ozone hole by chemistry-climate models
Antarctic ozone hole chemistry-climate models
2009/9/11
While chemistry-climate models are able to reproduce many characteristics of the global total column ozone field and its long-term evolution, they have fared less well in simulating the commonly used ...
Simulation of Mexico City plumes during the MIRAGE-Mex field campaign using the WRF-Chem model
Mexico City plumes MIRAGE-Mex field campaign WRF-Chem model
2009/7/22
The quantification of tropospheric O3 production in the downwind of the Mexico City plume is a major objective of the MIRAGE-Mex field campaign. We used a regional chemistry-transport model (WRF-Chem)...
Equilibrium of sinks and sources of sulphate over Europe: comparison between a six-year simulation and EMEP observations
sulphate Europe EMEP
2009/7/15
Sulphate distributions were simulated with a global chemistry transport model. A chemical scheme describing the sulphur cycle and the parameterisations of the main sinks for sulphate aerosols were inc...
Hydrogen cyanide in the upper troposphere: GEM-AQ simulation and comparison with ACE-FTS observations
Hydrogen cyanide GEM-AQ simulation ACE-FTS
2009/7/15
We investigate the spatial and temporal distribution of hydrogen cyanide (HCN) in the upper troposphere through numerical simulations and comparison with observations from a space-based instrument. To...
A simulation of the global distribution and radiative forcing of soil dust aerosols at the Last Glacial Maximum
global distribution radiative forcing soil dust aerosols Last Glacial Maximum
2009/5/15
In this study an integrated simulation of the global distribution and the radiative forcing of soil dust aerosols at the Last Glacial Maximum (LGM) is performed with an aerosol climate model, SPRINTAR...
Simulation of the climate impact of Mt. Pinatubo eruption using ECHAM5 – Part 2: Sensitivity to the phase of the QBO and ENSO
Mt. Pinatubo eruption ECHAM5 QBO ENSO
2009/5/15
The sensitivity of the climate impact of Mt. Pinatubo eruption in the tropics and extratropics to different QBO phases is investigated. Mt. Pinatubo erupted in June 1991 during the easterly phase of t...
Laboratory investigation of photochemical oxidation of organic aerosol from wood fires 1: measurement and simulation of organic aerosol evolution
photochemical oxidation organic aerosol wood fires organic aerosol evolution
2009/3/13
Experiments were conducted to investigate the effects of photo-oxidation on organic aerosol (OA) emissions from flaming and smoldering hard- and soft-wood fires under plume-like conditions. This was d...
Simulation of dust aerosol and its regional feedbacks over East Asia using a regional climate model

2009/3/13
The ICTP regional climate model (RegCM3) coupled with a desert dust aerosol model is used to simulate the net radiative forcing (short-wave and long-wave) and related climate effects of dust aerosols ...
Methane plume over south Asia during the monsoon season: satellite observation and model simulation
Methane plume south Asia monsoon season
2009/3/13
Satellite retrievals of methane (CH4) using the Atmospheric Infrared Sounder (AIRS) on the EOS/Aqua platform from 2003–2007 show a strong, plume-like enhancement of CH4 in the middle to upper troposph...
