Abstract: A method of characterizing an aerosol, the method comprising illuminating aerosol particles (118) located within a measurement volume with a first electromagnetic radiation pulse (114) emitted from a first source (102) and receiving one or more electromagnetic radiation returns that have been scattered by the aerosol particles illuminated by the first electromagnetic radiation pulse at one or more sensors (106, 108), illuminating the aerosol particles within the measurement volume with a second electromagnetic radiation pulse (116) emitted from a second source (104) and receiving a one or more electromagnetic radiation returns scattered by the aerosol particles illuminated by the second electromagnetic radiation pulse at the one or more sensors, determine at least one of intensity based on the one or more electromagnetic radiation returns, and determine an aerosol parameter based on an algorithm and the at least one intensity.

Abstract: Apparatus and associated methods relate to determining an effective size, quantity, shape, and type of water particles in a cloud atmosphere based on differences in amplitudes of optical signals backscattered at different backscattering angles. Off-axis backscattering - backscattering at angles other than 180 degrees - is affected by the effective size, quantity, shape, and type of water droplets. Detected amplitudes of optical signals that are backscattered at different angles are used to indicate the effective size, quantity, shape, and type of water particles in the cloud atmosphere. In some embodiments, optical emitters and detectors are configured to measure amplitudes of optical signals backscattered at backscattering angles of both on-axis - 180 degrees - and off-axis varieties.
