WebNov 10, 2024 · 3. Influence and analysis of atmospheric attenuation Atmospheric attenuation is one of the factors that have a greater impact on the detection range of lidar. When the laser beam passes through the atmospheric medium, atmospheric molecules and aerosol particles will absorb and scatter the laser beam, resulting in weakening of the … WebJul 9, 2015 · (f) Atmospheric attenuation: atmospheric attenuation is the resultant of fog and haze normally. It also depends upon dust and rain. It is supposed that atmospheric attenuation is wavelength dependent but this is not true. Haze is wavelength dependent. Attenuation at 1550nm is less than other wavelengths in haze weather condition [ 11 ].
