Res. 93, 5159-5166http://hdl.handle.net/10315/2959New field measurements of atmospheric OH radicals by laser long-path absorption spectroscopy are reported: In the Black Forest, diurnal profiles of OH radical concentrations ranging up to 8.7 × 106 cm−3 have been observed during June 1984. Simultaneous measurements of other trace gases, photolysis frequencies, and meteorologic parameters were also made to allow comparison of observed OH levels with model calculations.enArticlehttp://www.agu.org/journals/jd/http://www.agu.org/journals/jd/v093/iD05/JD093iD05p05159/
