Abstract

Measurements of low-altitude cloud and its interaction with aerosol are analyzed with a multiple-wavelength elastic- Raman scattering lidar. Using the numerical experiment approach, we first evaluate the retrieval accuracy of cloud extinction from the Raman-lidar algorithms, in particular at the cloud edges. For the low-level water-phase cloud, the simulation also shows the dramatic variation of lidar-ratio, color-ratio and extinction-ratio with the small droplets and their correlation. Then, the measurement examples by CCNY elastic-Raman lidar illustrate that the small droplets probably appear at the cloud edges, which might imply the new particle formation or the cloudaerosol interaction.
