چکیده انگلیسی
The present paper has used a comprehensive approach to study atmosphere pollution sources including the study of vertical distribution characteristics, the epicenters of occurrence and transport of atmospheric aerosol in North-West China under intensive dust storm registered in all cities of the region in April 2014. To achieve this goal, the remote sensing data using Moderate Resolution Imaging Spectroradiometer satellite (MODIS) as well as model-simulated data, were used, which facilitate tracking the sources, routes, and spatial extent of dust storms. The results of the study have shown strong territory pollution with aerosol during sandstorm. According to ground-based air quality monitoring stations data, concentrations of PM10 and PM2.5 exceeded 400â¯Î¼g/m3 and 150â¯Î¼g/m3, respectively, the ratio PM2.5/PM10 being within the range of 0.123-0.661. According to MODIS/Terra Collection 6 Level-2 aerosol products data and the Deep Blue algorithm data, the aerosol optical depth (AOD) at 550â¯nm in the pollution epicenter was within 0.75-1. The vertical distribution of aerosols indicates that the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) 532â¯nm total attenuates backscatter coefficient ranges from 0.01 to 0.0001â¯kmâ1â¯Ãâ¯srâ1 with the distribution of the main types of aerosols in the troposphere of the region within 0-12.5â¯km, where the most severe aerosol contamination is observed in the lower troposphere (at 3-6â¯km). According to satellite sounding and model-simulated data, the sources of pollution are the deserted regions of Northern and Northwestern China.
