Characterization of the middle and upper atmosphere …

WebThe lidar equation relates the number of received photocounts to the atmospheric density by the lidar equation: . Here is a constant which depends on the individual lidar system, the type of scattering (here Rayleigh scattering) and the transmission of the atmosphere, z is height and N(z) is the number of photocounts at each height. WebLIDAR uses light in the same way. The idea to use light and measure how long it took the light to return in order to find distance originated with a man named EH Synge, who in 1930 used searchlights to study the atmosphere. In keeping with the atmosphere, light pulses were used in 1938 to measure the heights of clouds.
