  1. Summary of Lidar BG - 1 • Donovan, O’Connor, Comstock, Delenoë, Preißler, and Seifert • Could discuss many different types of lidars: decided to focus discussion on elastic backscatter lidars • Sy matrix: • Most systems will be Poisson limited with off-diagonal being zero (no correlation between different heights) • Could validate this by collecting high temporal resolution data and confirming with autocorrelation or power-spectral analysis • Uncertainties in the overlap, which are “random” when considered over long time scales, contribute to correlated error in the lowest altitude bins • How to determine the calibration coefficient of the lidar? • Afterpulse uncertainties? • Dead-time uncertainties?

  2. Summary of Lidar BG - 2 • Forward model issues: • Backscatter phase function • Different habits, particle size distributions, etc • Different cloud regimes, temperatures, etc • Multiple scattering corrections • Uncertainties associated with lidar field-of-view • Uncertainties associated with size of scattering particle • Discussion of laser not perfectly aligned in center of detector FOV • Need a review article on MS corrections for lidar
