Sun, CK; Sun, L (2012). Aerosol Optical Thickness Retrieval Based on Hj-Ccd Supported by Modis Surface Reflectance Production. ADVANCED MATERIALS IN MICROWAVES AND OPTICS, 500, 843-847.

For lack of short-wavelength-IR bands near 2.1 mu m, the operational capabilities of HJ-1A/B CCD in monitoring aerosols are limited overwhelmingly. To solve this problem, a new algorithm, using MODIS surface reflectance production (MOD09) to support HJ-1A/B CCD aerosol retrieval, is proposed. A model of determining HJ-1 A/B CCD surface reflectance at blue band using MODIS surface reflectance data based on the kernel-based BRDF model is proposed. Six different HJ-1A/B CCD images, which have a high-quality and cover almost all the areas in Beijing, are used to test the new method. The retrieved values are compared with the API of Beijing city. Both of them have a similar variation trend. Implementation of the algorithm has a great significance in promoting the operational running of monitoring aerosol
