Simulation of the aerosol spaceborne lidar Tectonica-A

摘要

Abstract: The aim of the project `Tectonica-A' is the development of the technique and the creation of a spaceborne lidar for determining the sites of enhanced concentration of surface aerosols. The lidar data combined with the data of different sensors (spaceborne and ground-based) will be used for the short-term forecast of the earthquakes. Using the requirements for the lidar `Tectonica-A' the computer simulation was made of the operation of the elastic scattering multifrequency lidar in orbit at 600 km altitude. The need for selection of no less than three sounding wavelengths in the range of 300 - 1000 nm is shown. The lidar potential is justified to meet the demand for the necessary space resolution. Besides, the program of physical modeling of the lidar `Tectonica' was developed for the study of dynamics of the aerosol concentration in the atmospheric boundary layer in the seismic active area of Russia (the lake Baikal). The optical observations are combined with the simultaneous measurements of the electromagnetic radiation intensity of the Earth's crust.!15
