Light detection and ranging (Lidar) is an active remote sensing tool that has been widely
used for atmospheric studies for over 50 years. Lidar, the optical counter part of more
familiar radar technique uses laser light for remote sensing of the atmosphere. A lidar
system transmits a pulse of light into the atmosphere and analyzes the backscatter signal
intensity from clouds, aerosols, and molecules as a function of time. The micropulse lidar
(MPL) system is a compact and eye safe lidar capable of measuring the atmospheric
constituents remotely using low energy laser pulses. This discussion will focus primarily
on a brief overview of the MPL system and its applications for scientific studies and
environmental monitoring.
