Aerosol optical depth retrieval over land from two angle view satellite radiometry

摘要

Atmospheric aerosol particles play an important role in the Earth’s radiation balance.They are considered one of the largest uncertainties in today’s climate modelling. To a largeextent, these uncertainties are caused by the lack of aerosol data on a global scale. Due to the short lifetimes of aerosols in the troposphere (hours to a week), and the many different sources with different spatial extents and emissions, the aerosol is highly variable in both space andtime. Satellite remote sensing only can provide the global coverage and the spatial andtemporal resolution to measure the inhomogeneous aerosol fields.
