Integration of MODIS Aerosol Products for Estimating Impact of the Russian Wildfires over Europe and Asia during August 2010

摘要

A series of wildfires broke out in western Russia starting in late July, 2010. Detrimental particulates and gases released into the local Russian atmosphere and possible impact to the global atmosphere environment during this period have been reported. In this paper, an extremely hazy area and its transport trajectory were observed using Moderate Resolution Imaging Spectroradiometer (MODIS) colour composite image, integrated MODIS aerosol products based on Kalman filtering, HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model and Second Simulation of the Satellite Signal in the Solar Spectrum (6S) model. The advection and dispersion of the plume causing by Russian wildfires and its effect to local, regional and global atmospheric environment were analysed according to AOD, visibility and PM data. The result showed that the wildfires had an extremely bad influence to western Russia; however, little impact was obtained to most European and Asian parts except some neighboring countries.
