| Abstract: | Lidar is a powerful technique for the study of atmospheric structure and dynamics. The spatial and temporal variability of
minor constituents of the atmosphere such as aerosols, dusts, clouds, water vapour, and wind speed and temperature structure
of the upper atmosphere can be studied using lidar. This article describes the basic principle of lidar operation, types of
laser used for the remote sensing of the atmosphere and mechanism of scattering/absorption processes when the laser interacts
with the atmosphere. Part 1 gives the basics and applications of lidar. Also, one type of lidar—Mie and Rayleigh lidar is
described.

research involves the study of aerosols, dusts, and clouds in the lower atmosphere and temperature structure in the upper
atmosphere. |
