Retrieval of Aerosol Optical Depth over Urban Areas Using Terra/modis Data

Satellite remote sensing retrieval has shown excellent competence at retrieving the aerosol distribution and properties comparing with traditional detection. The extended dark dense vegetation (DDV) algorithm for MODIS data was used widely all over the world. However, whether this algorithm can be transferred to high reflectivity areas of China is not known yet, especially in urban area and its surroundings. In this paper, we attempt to derive Aerosol Optical Depths (AOD) by exploiting the extended dense vegetation algorithm and TERRA/MODIS data. Preliminary validation results by comparing with in situ measured data show good accuracy and promising potential in different seasons of China urban areas. * Corresponding author.
