The Study On V5.2Algorithm For Aerosol Optical Depth In Shanghai With Remote Sensing Image

With the economic development, environmental pollution problems begin toemerge, over the past few years, environmental pollution has become an importanttask for the international community to be mentioned, The environmental pollutionto the harm to human life and health is increasingly serious, therefor thesolution to the environmental pollution problems has reached a critical state.On China itself, since the reform and opening up, China is trying to implementthe " sustainable development" strategy, but the actual situation is not verysatisfactory, serious environmental problems is an important factor restrictingChina’s economic development, so the monitoring of environmental issues andgovernance issues has become Chinese seeking the path of development problemswhich can not be ignored. Compared to foreign countries, the monitoring ofenvironmental pollution, especially air pollution monitoring started late, thetraditional monitoring stations and equipment can not meet the current variability ofatmospheric pollution, satellite remote sensing data to stabilize its breadth, theimage and rapid access to information is rapidly becoming the primary means ofatmospheric pollution monitoring. The successful formation of1,2,3satelliteFengyun successful launch and subsequent resource satellites, meteorologicalsatellites and three marine satellite remote sensing satellite series also mark thecountry in the field of satellite remote sensing to monitor atmospheric pollutionefforts and achievements.This paper selects the source for the study of Shanghai, the use of algorithmsand6S V5.2transmission model as a research method combined MODIS L1B dataon satellite images of Shanghai aerosol inversion of aerosol optical depth study ofShanghai.Firstly, the composition and structure will be carried out from the MODIS L1Bdata analysis, interpretation of satellite remote sensing data sources aerosol optical thickness, and a brief description of the formation mechanism of6S transmissionmodel, while the simple algorithm described V5.2.Secondly, we will conduct experimental analysis of the feasibility of Shanghaiaerosol optical depth from inversion experiment will be selected during the eightdays of2010-2011as a research data source, its AOD inversion and inversion ofvalues and AERONET comparison of observations made. Feasibility inversion fromthe accuracy analysis.Finally, in the presence of feasibility, this paper will select the neighboring cityof Shanghai city as the contrast data sources of aerosol optical thickness retrieval,and combine with the inversion value to elaborate the relevance of aerosolconcentration space in Shanghai city.
