Abstract:
A 2.5 THz heterodyne system originally designed for astronomical purposes was modified and further developed for atmospheric measurements. In several flights it was successfully used aboard the research aircraft FALCON at flight altitudes between 11km and 12 km and with pointing angles between 5° and 20° versus horizon. The thermal emission of the hydroxyl radical OH at 2.514 THz was received. The latest results show a sufficient signal-to-noise ratio that OH concentration profile can be retrieved.
