This Review aims to summarize the current understanding of bulk tropospheric aqueous-
phase chemistry. Because a complete review of all developments in this area would be …

The hydroxyl radical, OH, initiates the removal of the majority of trace gases in the
atmosphere, and together with the closely coupled species, the hydroperoxy radical, HO2, is …

Aerosol− cloud interactions account for the largest uncertainty in current estimates of
changes in radiative forcing according to the most recent IPCC report. 1 The term “aerosol …

Measurements of OH, HO 2, complex RO 2 (alkene-and aromatic-related RO 2) and total RO
2 radicals taken during the integrated Study of AIR Pollution PROcesses in Bei**g …

Wintertime in situ measurements of OH, HO 2 and RO 2 radicals and OH reactivity were
made in central Bei**g during November and December 2016. Exceptionally elevated NO …

The hydroperoxyl radical (HO 2) is a major precursor of OH and tropospheric ozone. OH is
the main atmospheric oxidant, while tropospheric ozone is an important surface pollutant …

We use 2005–2009 satellite observations of formaldehyde (HCHO) columns from the OMI
instrument to infer biogenic isoprene emissions at monthly 1× 1° resolution over the African …

Measurements of OH, HO 2, RO 2 i (alkene and aromatic-related RO 2) and total RO 2
radicals taken during the ClearfLo campaign in central London in the summer of 2012 are …

Observations of the tropical atmosphere are fundamental to the understanding of global
changes in air quality, atmospheric oxidation capacity and climate, yet the tropics are under …

The aim of this work is the investigation of the detailed mechanisms for the initiation reaction
leading to the spontaneous combustion of lignite. To carry this out we have used the ReaxFF …
