Ambient OH and HO 2 concentrations were measured by laser induced fluorescence (LIF)
during the PRIDE-PRD2006 (Program of Regional Integrated Experiments of Air Quality …

HO 2 concentration measurements are widely accomplished by chemical conversion of HO
2 to OH including reaction with NO and subsequent detection of OH by laser-induced …

During June, July and August 2006 five aircraft took part in a campaign over West Africa to
observe the aerosol content and chemical composition of the troposphere and lower …

A three channel broadband cavity enhanced absorption spectroscopy (BBCEAS) instrument
has been developed for airborne measurements of atmospheric trace gases involved in …

Hydroxyl and hydroperoxy radicals are key species for the understanding of atmospheric
oxidation processes. Their measurement is challenging due to their high reactivity; therefore …

Isoprene is the predominant non-methane volatile organic compound emitted to the
atmosphere and shapes tropospheric composition and biogeochemistry through its effects …

The hydroxyl radical (OH) plays a key role in the oxidation of trace gases in the troposphere.
However, observations of OH and the closely related hydroperoxy radical (HO 2) have been …

We describe a new instrument for the quantification of atmospheric peroxy radicals (HO2,
CH3O2, C2H5O2, etc.) using the chemical amplification method. Peroxy radicals are mixed …

Peroxy radicals play important roles in the atmospheric oxidation of organic compounds and
the formation of ozone and secondary organic aerosol. There are few peroxy radical …

During the" African Monsoon Multidisciplinary Analysis"(AMMA) field phase in August 2006,
a variety of measurements focusing on deep convection were performed over West Africa …
