What is LIDAR?
Stands for LIght Detection And Ranging
Micropulse LASERs
Measurements of (usually) backscatter from clouds and aerosols in the transmission path
LIDAR systems
ground-based (this lecture): MPLNET (colocated with AERONET sites), other unaffiliated LIDARs
space-based: CALIPSO (next half of the lecture)
Kinds of LIDAR
backscatter LIDAR
differential absorption LIDAR (DIAL)
Doppler LIDAR
fluorescence LIDAR
Raman LIDAR
Differential Absorption LIDAR (DIAL)
Calculation of molecular species in the atmosphere
Transmit pulses at two different frequencies determined by the absorption line of the species you want to measure
