A system includes an optical ice detection (OID) sub-system optically coupled to light collection optics. A water vapor differential absorption LIDAR (WV-DIAL) sub-system is optically coupled to the OID 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 aboard 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.
