Evaluation of a new JMA aircraft flask sampling system and laboratory trace gas analysis system [PDF]
We established and evaluated a flask air sampling system on a cargo C-130H aircraft, as well as a trace gas measurement system for the flask samples, as part of a new operational monitoring program of the Japan Meteorological Agency (JMA).
