| Abstract: | Atmospheric aerosol optical depth change has great influence on the accuracy of Earth observation, and is one of the research hotspots of quantitative remote sensing. However, traditional atmospheric radiative transfer softwares such as 6S and MODTRAN choose horizontal meteorological visibility as the key optical property parameters of aerosol. Hence, thorough discussion of the relationship between aerosol optical depth and horizontal meteorological visibility has important practical significance. Four convert models are validated by measurements of horizontal meteorological visibility and synchronous AOD of MODIS. Results show that Peterson model with atmosphere scale height H can obtain higher accuracy. |
