• Modeling daytime and nighttime secondary organic aerosol formation via multiphase reactions of biogenic hydrocarbons.

  Authors:Sanghee Han and Myoseon JangFrom:Atmospheric Chemistry and Physics (Vol. 23, Issue 2) Peer-Reviewed

  Jan. 24, 2023440 words Article The daytime oxidation of biogenic hydrocarbons is attributed to both OH radicals and O.sub.3, while nighttime chemistry is dominated by the reaction with O.sub.3 and NO.sub.3 radicals. Here, daytime and nighttime...

• Nitrogen oxides in the free troposphere: implications for tropospheric oxidants and the interpretation of satellite NO.sub.2 measurements.

  Authors:Viral Shah, Daniel J. Jacob, Ruijun Dang, Lok N. Lamsal, Sarah A. Strode, Stephen D. Steenrod, et al.From:Atmospheric Chemistry and Physics (Vol. 23, Issue 2) Peer-Reviewed

  Jan. 24, 2023644 words Article Satellite-based retrievals of tropospheric NO.sub.2 columns are widely used to infer NO.sub.x (â¡ NO + NO.sub.2) emissions. These retrievals rely on model information for the vertical distribution of NO.sub.2 . The free...

• Monitoring sudden stratospheric warmings under climate change since 1980 based on reanalysis data verified by radio occultation.

  Authors:Ying Li, Gottfried Kirchengast, Marc Schwaerz, and Yunbin YuanFrom:Atmospheric Chemistry and Physics (Vol. 23, Issue 2) Peer-Reviewed

  Jan. 24, 2023481 words Article We developed a new approach to monitor sudden stratospheric warming (SSW) events under climate change since 1980 based on reanalysis data verified by radio occultation data. We constructed gridded daily mean temperature...

• Physicochemical properties of charcoal aerosols derived from biomass pyrolysis affect their ice-nucleating abilities at cirrus and mixed-phase cloud conditions.

  Authors:Fabian Mahrt, Carolin Rösch, Kunfeng Gao, Christopher H. Dreimol, Maria A. Zawadowicz, and Zamin A. KanjiFrom:Atmospheric Chemistry and Physics (Vol. 23, Issue 2) Peer-Reviewed

  Jan. 24, 2023356 words Brief article Atmospheric aerosol particles play a key role in air pollution, health, and climate. Particles from biomass burning emissions are an important source of ambient aerosols, have increased over the past few decades, and are...

• Mercury in the free troposphere and bidirectional atmosphere-vegetation exchanges - insights from Maïdo mountain observatory in the Southern Hemisphere tropics.

  Authors:Alkuin M. Koenig, Olivier Magand, Bert Verreyken, Jerome Brioude, Crist Amelynck, Niels Schoon, et al.From:Atmospheric Chemistry and Physics (Vol. 23, Issue 2) Peer-Reviewed

  Jan. 24, 2023384 words Brief article Atmospheric mercury (Hg) observations in the lower free troposphere (LFT) can give important insights into Hg redox chemistry and can help constrain Hg background concentrations on a regional level. Relatively continuous...
