Aerosol optical depth determined by integration of the HJ CCD and IRS data

Monitoring of aerosols in a large-region can be achieved by remote sensing, which is very important to the regional ecology and environment study. Data obtained from environment and disaster monitoring and forecasting satellite, which was launched in September 2008, has the advantages of high temporal resolution and spatial resolution in comparison with the common remote sensing data which are used to estimate AOD like TM, MODIS and so on. In order to promote the application of HJ data in land aerosol area, a method combining the HJ CCD data and IRS (a sensor which is also carried by HJ satellite) 1.6 mu m data to estimate AOD was presented.
