Spectral and Spatial Dependency of Aerosol Extinction in the Upper Troposphere Based on the Moon Surface Photometry in the Earth's Umbra

摘要

The work is based on photometry of the Moon's surface during the total lunar eclipse of June 15, 2011. Photometric data are used to retrieve the value of aerosol extinction coefficient in the troposphere above the Earth's limb in various spectral bands in the optical and near-I R ranges. The results are analyzed in comparison with the data of previous eclipses in 2004-2008. The main result consists in an increased aerosol concentration in the South-East Asia, which is maximum among all eclipses observed in recent years. At the same time, no relationship between eclipse brightness and solar activity is observed, as well as unified latitude dependency of umbra brightness noticed earlier.
