Comparing methods for retrieving aerosol extinction coefficient with U.S. Standard Atmospheric Model and Temperature Gradient

Aerosol extinction coefficient in troposphere is retrieved from Raman-Mie lidar returns. Both the basic principle and the two retrieving methods are introduced in this paper. Calculated by U.S. Standard Atmospheric Model and Temperature Gradient, the latter of which means temperature value may decrease with the rising of the altitude, their results are compared so that the differences between the two can be clearly seen. A more suitable condition, which matches the U.S. Standard Atmospheric Model more and which matches Temperature Gradient, is presented.
