Oxidation of biogenic volatile organic compounds (BVOC) by the nitrate radical (NO 3)
represents one of the important interactions between anthropogenic emissions related to …

Abstract The Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS) officially
became the 33rd European Research Infrastructure Consortium (ERIC) on 25 April 2023 …

Chemical mechanisms form the core of atmospheric models to describe degradation
pathways of pollutants and ultimately inform air quality and climate policymakers and other …

Radicals and their precursors play a central role in the chemical transformations occurring in
indoor air and on indoor surfaces. Such species include OH, HO2, peroxy radicals, nitrous …

Hydroxyl (OH) radical reactivity (k OH) has been measured for 18 years with different
measurement techniques. In order to compare the performances of instruments deployed in …

Heterogeneous N2O5 uptake onto aerosol is the primary nocturnal path for removal of NOx
(= NO+ NO2) from the atmosphere and can also result in halogen activation through …

A small and portable incoherent broadband cavity-enhanced absorption spectrometer
(IBBCEAS) for NO 3 and N 2 O 5 measurement has been developed. The instrument …

We report the characteristics and performance of a newly developed five-channel cavity ring-
down spectrometer to detect NO 3, N 2 O 5, NO 2, total peroxy nitrates (ΣPNs) and total alkyl …

We have analyzed near-global stratospheric data (and mesospheric data as well for H 2 O)
in terms of absolute abundances, variability, and trends for O 3, H 2 O, HCl, N 2 O, and HNO …

A new, two-channel instrument for simultaneous NO 3 and N 2 O 5 monitoring was used to
make the first comprehensive set of nocturnal NO x measurements (NO, NO 2, NO 3 and N 2 …
