Diurnal variability, photochemical production and loss processes of hydrogen peroxide in the boundary layer over Europe

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 11953-11968 (2019)

Hydrogen peroxide (H2O2) plays a significant role in the oxidizing capacity of the atmosphere. It is an efficient oxidant in the liquid phase and serves as a temporary reservoir for the hydroxyl radical (OH), the most important oxidizing agent in the

Direct measurements of NO3 reactivity in and above the boundary layer of a mountaintop site: identification of reactive trace gases and comparison with OH reactivity

Autor: J. M. Liebmann, J. B. A. Muller, D. Kubistin, A. Claude, R. Holla, C. Plass-Dülmer, J. Lelieveld, J. N. Crowley

Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 12045-12059 (2018)

We present direct measurements of the summertime total reactivity of NO3 towards organic trace gases, kOTGNO3, at a rural mountain site (988 m a.s.l.) in southern Germany in 2017. The diel cycle of kOTGNO3 was strongly influenced by local met

A novel semi-direct method to measure OH reactivity by chemical ionization mass spectrometry (CIMS)

Autor: J. B. A. Muller, T. Elste, C. Plass-Dülmer, G. Stange, R. Holla, A. Claude, J. Englert, S. Gilge, D. Kubistin

Publikováno v: Atmospheric Measurement Techniques, Vol 11, Pp 4413-4433 (2018)

An operational chemical ionization mass spectrometer (CIMS) for hydroxyl radical (OH) and sulfuric acid (H2SO4) concentration measurements was adapted to include observations of OH reactivity, which is the inverse of OH lifetime, for long-term mon

Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 1835-1861 (2018)

This paper revisits the atmospheric new particle formation (NPF) process in the polluted Central European troposphere, focusing on the connection with gas-phase precursors and meteorological parameters. Observations were made at the research statio

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Pp 7807-7826 (2017)

We analysed the extensive dataset from the HUMPPA-COPEC 2010 and the HOPE 2012 field campaigns in the boreal forest and rural environments of Finland and Germany, respectively, and estimated the abundance of stabilised Criegee intermediates (SCIs)
