Overview

Bistatic lidar measures aerosol optical depth in the atmosphere, suggesting new observational methods.

Key Points

  • The aim is to observe atmospheric aerosols and compare the findings with established aerosol optical depth data.
  • Utilized a bistatic camera lidar system with a continuous wave laser and CCD camera detector.
  • Measured nighttime laser light scattering to observe atmospheric aerosols.
  • Tracked scatterer altitude using geometry.
  • Normalized signals to a molecular model at high altitudes and applied transmission correction.
  • Converted side-scatter data to total scatter using aerosol scattering phase functions from AERONET.
  • Successfully derived aerosol optical depth from lidar observations.
  • Compared results with NASA MERRA2 and AERONET data, indicating consistency in aerosol measurements.
  • Identified potential improvements in aerial observation techniques.
