abstract = {The free radicals OH, HO2, RO2, and NO3 are known to be the
driving force for most chemical processes in the atmosphere.
Since the low concentration of the above radicals makes
measurements particularly difficult, only relatively few
direct measurements of free radical concentrations have been
reported to date. We present a comprehensive set of
simultaneous radical measurements performed by Laser Induced
Fluorescence (LIF), Matrix Isolation - Electron spin
Resonance (MI-ESR), Peroxy Radical Chemical Amplification
(PERCA), and Differential Optical Absorption Spectroscopy
(DOAS) during the BERLIner OZonexperiment (BERLIOZ) during
July and August of 1998 near Berlin, Germany. Most of the
above radical species were measured by more than one
technique and an intercomparison gave good agreement. This
data set offered the possibility to study and quantify the
role of each radical at a rural, semi-polluted site in the
continental boundary layer and to investigate
interconnections and dependencies among these free radicals.
In general (box) modelled diurnal profiles of the different
radicals reproduced the measurements quite well, however
measured absolute levels are frequently lower than model
predictions. These discrepancies point to disturbing
deficiencies in our understanding of the chemical system in
urban air masses. In addition considerable night-time peroxy
radical production related to VOC reactions with NO3 and O-3
could be quantified.},
