摘要：

First remote measurements of stratospheric OH with an airborne vertical sounding far-infrared (FIR) heterodyne spectrometer are reported: Thermal emission from rotational transitions at 2,514 GHz were observed. The measurements were carried out from aboard the DLR jet aircraft FALCON at about 11 km altitude flying over Germany. Temperature contrast was optimized by observing at elevation angles around 20 degrees. A previous feasibility study showed that improvements in stability and sensitivity will allow the determination of concentration profiles with an altitude resolution of about 10 km over an altitude range from 20 to 50 km.
