北京地区夏季气溶胶光学厚度反演
Retrieval of Aerosol Optical Depth over the Urban Area of Beijing in Summer
摘要
Abstract
The applicability of three kinds of atmospheric aerosol models to Beijing aerosol optical depth(i.e, AOD)inversion in summer was studied and compared based on 6S model.Firstly,the Terra-MODIS L1B data in summer were downloaded,whose spatial resolution was 1,km,and then three look-up tables(LUT)were created based on continental,marine and urban standardization aerosol models and the AOD values of Beijing in summer was retrieved using dense dark vegetation algorithm.After that,the accuracy of the retrieved results was verified against the real land AOD data from AERONET.The results showed that the AOD inversion results of marine model and continental aerosol model have the high relativity with AERONET data,and the correlation coefficient is 0.806,6 and 0.766,4,respectively.There wereobvious differences between the AOD inversion results of urban model and AERONET data;the correlation coefficient was only 0.482,5.The retrieved AOD results during clear days and haze/fog days were compared with AERONET data,which showed that it was more accurate to retrieve the AOD using the marine model on clear summer days over the urban area of Beijing.关键词
