Mega-cloud from Canadian wildfires will help model impacts of nuclear war（图）
Mega-cloud Canadian wildfires model impacts nuclear war
2019/10/21
Extreme wildfires in British Columbia, Canada, pumped so much smoke into the upper atmosphere in August 2017 that an enormous cloud circled most of the Northern Hemisphere – a finding reported in the ...
Impacts of mechanistic changes on HOx formation and recycling in the oxidation of isoprene
mechanistic changes HOx formation the oxidation of isoprene
2010/9/14
Recently reported model-measurement discrepancies for the concentrations of the HOx radical species (OH and HO2) in locations characterized by high emission rates of isoprene have indicated possible d...
Impacts of HONO sources on the photochemistry in Mexico City during the MCMA-2006/MILAGO Campaign
HONO sources the photochemistry Mexico City the MCMA-2006/MILAGO Campaign
2010/8/16
The contribution of HONO sources to the photochemistry in Mexico City is investigated during the MCMA-2006/MILAGO Campaign using the WRF-CHEM model. Besides the homogeneous reaction of NO with OH, fou...
Modelling the chemically aged and mixed aerosols over the eastern central Atlantic Ocean – potential impacts
the chemically aged and mixed aerosols the eastern central Atlantic Ocean
2010/8/13
Detailed information on the chemical and physical properties of aerosols is important for assessing their role in air quality and climate. This work explores the origin and fate of continental aerosol...
Modelling the impacts of ammonia emissions reductions on North American air quality
ammonia emissions reductions North American air quality
2009/10/9
A unified regional air-quality modelling system (AURAMS) was used to investigate the effects of reductions in ammonia emissions on regional air quality, with a focus on particulate-matter formation. T...
Update on emissions and environmental impacts from the international fleet of ships: the contribution from major ship types and ports
international fleet of ships major ship types ports
2009/3/31
A reliable and up-to-date ship emission inventory is essential for atmospheric scientists quantifying the impact of shipping and for policy makers implementing regulations and incentives for emission ...
Evaluation of the global oceanic isoprene source and its impacts on marine organic carbon aerosol
global oceanic isoprene source marine organic carbon aerosol
2009/3/13
We have combined the first satellite maps of the global distribution of phytoplankton functional type and new measurements of phytoplankton-specific isoprene productivities, with available remote mari...
Potential impacts of CF3I on ozone as a replacement for CF3Br in aircraft applications
CF3I ozone CF3Br aircraft applications
2009/1/15
Iodotrifluoromethane (CF3I) has been considered to be a candidate replacement for bromotrifluoromethane (CF3Br), which is used in aircraft for fuel inerting and for fire fighting. In this study, the c...
Impacts of using reformulated and oxygenated fuel blends on the regional air quality of the upper Rhine valley
reformulated and oxygenated fuel blends regional air quality upper Rhine valley
2009/1/9
The effects of using three alternative gasoline fuel blends on regional air quality of the upper Rhine valley have been investigated. The first of the tested fuels is oxygenated by addition of ethyl-t...
