Active and Passive Sensing of Aerosol from Space

摘要

It is well known that satellite methods are efficient means of remote monitoring of the atmospheric aerosol in real time. The algorithms of aerosol optical thickness (AOT) reconstruction from the data of NOAA/AVHRR radiometers recorded in the visible range of the spectrum have been developed and positive experience in their application for obtaining global information on the AOT of various regions of the global ocean has been accumulated (Afonin et al, 1997). On the other hand, there has been little and study on the applicability of these algorithms for monitoring of the aerosols above the Earth's underlying surface or interior water basins and also for aerosol classification. Undoubtedly, satellite measurements in the infrared range of the spectrum in combination with the data obtained in the visible range extend the capabilities of remote aerosol monitoring in the daytime and provide the basis for detecting local aerosol formations at night.
