Short summary
We developed a new way to measure ultrafine particles released by aircraft engines using an aerosol lidar sensor. This method allows us to quickly check emissions from a distance, without needing to collect samples directly from the engines. Our results show that this approach works well and could help airports and regulators better monitor air quality and reduce the environmental impact of aviation.
