Abstract

In recent years, regional haze weather appears frequently in China. The North China Plain is one of the four main regions in China heavily afflicted by haze. Since 2013, there have been many times of haze event in the North China Plain, and the quite severe haze pollution incidents took place in May 5-7, June 26-29 and September 28-30. This paper, investigates into these three severe haze episodes and their optical properties of aerosol. This research uses the Synergetic Retrieval of Aerosol Properties (SRAP) method to retrieve the Aerosol Optical Depth (AOD) from the Moderate Resolution Imaging Spectroradiometer (MODIS) data and also the AOD over Beijing areas with a 100 m × 100 m resolution by the synergetic use of small satellite data from the China HJ-1A/1B Charge-Coupled Device camera and Terra MODIS data. Beside the ground measurements of PM_2.5 were analyzed and the concentration of PM_2.5 was found up to 300 μg/m³ during the haze event.
