Abstract. The contribution of HONO sources to the photochemistry in Mexico City is investigated during MCMA-2006/MILAGO Campaign using WRF-CHEM model. Besides homogeneous reaction NO with OH, four additional are considered model: secondary formation from NO2 heterogeneous semivolatile organics, freshly emitted soot, on aerosol and ground surfaces. model five performs reasonably well tracking observed diurnal variation concentrations. included found significantly improve HOx (OH+HO2)...
Abstract. In the present study, impact of aerosols on photochemistry in Mexico City is evaluated using WRF-CHEM model for period from 24 to 29 March during MCMA-2006/MILAGRO campaign. An aerosol radiative module has been developed with detailed consideration size, composition, and mixing. The coupled into calculate optical properties, including depth, single scattering albedo, asymmetry factor. Calculated properties are good agreement surface observations aircraft satellite measurements...
Abstract. Organic aerosol concentrations are simulated using the WRF-CHEM model in Mexico City during period from 24 to 29 March association with MILAGRO-2006 campaign. Two approaches employed predict variation and spatial distribution of organic concentrations: (1) a traditional 2-product secondary (SOA) non-volatile primary aerosols (POA); (2) non-traditional SOA including volatility basis-set modeling method which components assumed be semi-volatile photochemically reactive distributed...
Abstract. The MIRAGE-Shanghai experiment was designed to characterize the factors controlling regional air pollution near a Chinese megacity (Shanghai) and conducted during September 2009. This paper provides information on measurements for this study. In order have some deep analysis of measurements, chemical/dynamical model (version 3 Weather Research Forecasting Chemical – WRF-Chemv3) is applied results are intensively compared with evaluate capability calculating pollutants in Shanghai...
Abstract. The contribution of garbage burning (GB) emissions to chloride and PM2.5 in the Mexico City Metropolitan Area (MCMA) has been investigated for period 24 29 March during MILAGRO-2006 campaign using WRF-CHEM model. When MCMA 2006 official emission inventory without biomass is used simulations, model significantly underestimates observed particulate urban suburban areas. inclusion GB substantially improves simulations chloride; contributes more than 60% observation, indicating that it...
Abstract. Ambient surface level concentrations of isoprene (C5H8) were measured in the major forest regions located south Shanghai, China. Because there is a large coverage broad-leaved trees this region, high measured, ranging from 1 to 6 ppbv. A regional dynamical/chemical model (WRF-Chem) applied for studying effect such on ozone production city Shanghai. The evaluation shows that calculated agree with when are lower than 3 ppb, but underestimate measurements values higher ppb. Isoprene...
To achieve automatic diagnosis of plant diseases and improve the image recognition accuracy diseases, two kinds grape (grape downy mildew powdery mildew) wheat (wheat stripe rust leaf rust) were selected as research objects, was conducted based on processing pattern recognition. After preprocessing including compression, cropping denoising, K_means clustering algorithm used to segment disease images, then 21 color features, 4 shape features 25 texture extracted from images. Backpropagation...
Digital image recognition of plant diseases could reduce the dependence agricultural production on professional and technical personnel in protection field is conducive to development informatization. In order find out a method realize diseases, four kinds neural networks including backpropagation (BP) networks, radial basis function (RBF) generalized regression (GRNNs) probabilistic (PNNs) were used distinguish wheat stripe rust from leaf grape downy mildew powdery based color features,...
Lidar measurements were made at Dunhuang (40°00′N, 94°30′E), China, to understand the vertical distribution of aerosols in free troposphere over Taklamakan desert summer 2002. The distributions scattering ratio suggested that particulate matter distributed from near ground about 6 km range values 2 5 and rapidly decreased 1 km. depolarization indicated dust particles a aerosol layer, particle layer A very clear boundary was also identified ratio. Particulate materials directly collected with...
Abstract. The purpose of the present study is to investigate uncertainties in simulating secondary organic aerosol (SOA) Mexico City metropolitan area (MCMA) due meteorological initial using WRF-CHEM model through ensemble simulations. simulated periods (24 and 29 March 2006) represent two typical episodes ("Convection-South" "Convection-North", respectively) basin during MILAGRO-2006 field campaign. aerosols are a non-traditional SOA including volatility basis-set modeling method...
Abstract. The local and regional impacts of open fires trash burning on ground-level ozone (O3) fine carbonaceous aerosols in the Mexico City Metropolitan Area (MCMA) surrounding region during two high fire periods March 2006 have been evaluated using WRF-CHEM model. model captured reasonably well measurement-derived magnitude temporal variation biomass organic aerosol (BBOA), simulated (OA) were consistent with many observation-based estimates. We did not detect significant effects surface...
Measurements of aerosol morphology and chemical elements were made in August 2002 at Dunhuang (40°00′N, 94°30′E), China, on the basis direct sampling free tropospheric aerosols with a balloonborne particle impactor, to understand nature atmospheric particles over desert areas Asian continent. Electron microscopic experiments directly showed that mineral (dust) major constituents coarse mode troposphere Taklamakan desert. Typical types particles, according energy dispersive X‐ray (EDX)...

Abstract The southwest vortex (SWV) is a critical weather system in China, but our knowledge of this remains incomplete. Here, we investigate the cloud properties SWV. First, search for SWVs with time steps and center locations that are consistent between SWV yearbook ERA-Interim reanalysis data. Second, supplement these SWVs’ life spans movement paths. Third, relocate Fengyun (FY) satellite FY-4A retrievals 10° × region centered on each analyze occurrence frequency (COF), cloud-top height...
