中国海域MODIS气溶胶光学厚度检验分析
Validation of MODIS Aerosol Optical Depth Retrievals over the China Sea
摘要
Abstract
The Aerosol Robotic NETwork(AERONET) provides the necessary ground-based observa-tion to validate and assess the applicability of the latest version MODIS Collection 005 aerosol optical thickness(AOT) products over the China sea for the fist time. Based on the two kinds of data,the methods of validation over the China Sea are discussed. The validation results show that the MODIS Collection 005 AOT has a good relationship with the AERONET AOT, and their correlation coefficient is greater than 0. 9 over the China sea. By testing different validation methods, we find that the window size of MODIS data can influence the validation result,and the 30 km ×30 km window size is the best over the China sea. Finally, the comparison of MODIS-and AERONET-derived AOT respectively overdifferent regions of the China Sea suggests that the MODIS Collection 005 AOT at 550 nm correspondwith the error standard of NASA and most of its error can be controlled under±0. 05±0. 05τ-over the China Sea, so MODIS Collection 005 AOT is creditable over the China Sea for science research.关键词
