Determination of Backscatter-Extinction Coefficient Ratio for LIDAR-Retrieved Aerosol Optical Depth Based on Sunphotometer Data

Backscattered power data from the Doppler LIght Detection And Ranging (LIDAR) systems at the Hong Kong International Airport (HKIA) could be used to obtain the extinction coefficient of the troposphere by combining with the meteorological optical range (MOR) data from the nearby forward scatter sensor. The Range-height Indicator (RHI) scan of the LIDAR is then utilized to derive the vertical pr...

Analysis of atmospheric dust and aerosol extinction

Context. It is known that the Canary Islands are normally affected by dominant winds flowing from north-northeast, that in some meteorological conditions, can transport sand from the Sahara desert at high altitude. The dust may affect the efficiency of the telescopes and decrease the transparency of the sky. Aims. To maximize the scientific return of the telescopes located at the Observatorio d...

Micro Pulse Lidar as a Tool for Active Remote Sensing of Atmospheric Particulate

Lidars have been employed in the investigation of instantaneous vertical structure of atmospheric particulate. Remote measurements of particle backscattering and aerosol extinction coefficient provide the altitude distribution of particles existence in the atmosphere. This paper describes the technology of micro pulse lidar employed for computation of altitude profiles of particle backscatterin...
