Open Path – Active Remote Sensing | Airyx
Open path instruments create a light path of up to several kilometers length to measure atmospheric trace gases like (no2, so2, o3, hcho, hono, h2o, bro, io) with high precision and time resolution. Typical applications are monitoring of emissions from traffic (e.g., at ship routes or motorways) or from industrial facilities, as well as scientific applications concerning atmospheric chemistry and/or ground-level validation of satellite remote sensing.
