Abstract
This paper presents a 2-year record (from September 1996 to July 1998) of atmospheric 14CO measurements on whole air samples taken at the Mt. Sonnblick observatory (3106 m), a remote high-altitude site in Central Europe. An overall measurement precision of ca. 1/4 molecule 14CO per cm3 air has been achieved. A few events including unexpectedly low CO and 14CO values in winter 1996/97 will be discussed in some detail incorporating stable isotope information. Since the amount of 14CO data available for the Northern Hemisphere (NH) is rather sparse, this most detailed long-term 14CO record for NH temperate latitudes may be a valuable contribution to the assessment of global atmospheric OH concentrations.
