在Julich上空（北纬51°，东经6°），通过307.995 nm处的Q1 2（A² +，v = O，X²，v = O）谱线的光学吸收，沿沿着7.8 km的路径在对流层低层探测到OH。探测极限取决于摄影曝光的质量，在最有利的情况下可达到2 · 106 cm−3。OH通常保持在4 · 106 cm−3以下，即平均检测限。但在1975年8月中旬至11月的观测期间，有几次观测到的浓度高达7 · 106 cm−3。
OH has been detected in the lower troposphere by optical absorption of the Q1 2 (A²Σ+, v = O, X²Π, v = O) line at 307.995 nm along a 7.8 km path above Julich (51° North, 6° East). The detection limit depended on the quality of the photographic exposure and reached 2 · 106 cm−3 in the most favourable cases. OH generally remained below 4 · 106 cm−3, the average detection limit. But on several occasions during the observation period from mid August to November 1975 concentrations up to 7 · 106 cm−3 were observed.
