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: A system includes an optical ice detection (OID) sub-system (102) optically coupled to light collection optics (108). A water vapor differential absorption LIDAR (WV-DIAL) sub-system (104) is optically coupled to the OlD laser source or light collection optics. The OID sub-system and the WV-DIAL sub-system share at least a portion of an optical path of the light source or through the light collection optics. The OID sub-system, the WV-DIAL sub-system, and the illumination and light collection optics can all be aboard an aircraft. A method includes using a set of illumination and light collection optics abord an aircraft to obtain data indicative of optical ice detection (OID) and water vapor differential absorption LIDAR (WV-DIAL), e.g. to detect contrail forming conditions for the aircraft and/or predict persistence of contrails from the aircraft.
