Cloud-Aerosols interactions by multiple scenarios approach

Abstract

Aerosols can play the role of cloud and ice condensation nuclei. This study shows a set of measurements and experiments analysis in remote sensing, in distinct scenarios of cloud cover during day/nightime measurements using lidar, visible all-sky camera and solar photometry. The retrieved products are studied to obtain aerosol optical and physical properties in the vicinity of clouds. In this approach cloud cover and optical properties should be retrieved as well as main features used for cloud pixel identi cation, e. g., Red-Blue Di erence, Red- Blue Ratio, Normalized Red-Blue Ratio, Saturation and Intensity. We show some case studies to illustrate this methodology.
