The contribution of HONO sources to the photochemistry in Mexico City is investigated during the MCMA2006/MILAGO Campaign using the WRF-CHEM model. Besides the homogeneous reaction of NO with OH, four additional HONO sources are considered in the WRF-CHEM model: secondary HONO formation from NO2 heterogeneous reaction with semivolatile organics, NO2 reaction with freshly emitted soot, NO2 heter...
We present results from and evaluate the performance of a 12-month, 12 km horizontal resolution year 2005 air pollution simulation for the contiguous United States using the WRF-Chem (Weather Research and Forecasting with Chemistry) meteorology and chemical transport model (CTM). We employ the 2005 US National Emissions Inventory, the Regional Atmospheric Chemistry Mechanism (RACM), and the Mod...
Abstract Air pollution, especially the particulate matter (PM 2.5 ) remains to be a severe problem for environmental managers and researchers because it causes many respiratory diseases even casualties huge economic losses. Therefore, is significant study distribution characteristics of regional PM analyze mutual influence relationship between some influencing factors including air humidity, wi...
Representing brown carbon absorption, photobleaching, and secondary organic aerosol formation in wildfire emissions results improved agreement between WRF-Chem simulations AERONET observations.
Abstract. The Weather Research and Forecasting model data assimilation (WRFDA) system, initially designed for meteorological assimilation, is extended aerosol the WRF coupled with chemistry (WRF-Chem). An interface between WRF-Chem WRFDA built Regional Atmospheric Chemistry Mechanism (RACM) Modal Aerosol Dynamics Model Europe (MADE) Volatility Basis Set (VBS) schemes. This article describes imp...
Impact of model resolution on chemical ozone formation in Mexico City; application of the WRF-Chem model X. Tie, G. Brasseur, and Z.

[1] Regional aerosol model calculations were made using the Weather Research and Forecasting (WRF)-Community Multiscale Air Quality (CMAQ) and WRF-chem models to study spatial and temporal variations of aerosols around Beijing, China, in the summer of 2006, when the Campaigns of Air Quality Research in Beijing and Surrounding Region 2006 (CAREBeijing) intensive campaign was conducted. Model cal...
Abstract. Atmospheric aerosols can exert an influence on meteorology and air quality through aerosol–radiation interaction (ARI) aerosol–cloud (ACI), this two-way feedback has been studied by applying coupled models. As one of the regions with highest aerosol loading in world, Asia attracted many researchers to investigate effects several models (WRF-Chem, WRF-CMAQ, GRAPES-CUACE, WRF-NAQPMS, GA...
