• Diurnal evolution of total column and surface atmospheric ammonia in the megacity of Paris, France, during an intense springtime pollution episode.

  Authors:Rebecca D. Kutzner, Juan Cuesta, Pascale Chelin, Jean-Eudes Petit, Mokhtar Ray, Xavier Landsheere, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 15) Peer-Reviewed

  Aug. 12, 2021537 words Article Ammonia (NH.sub.3) is a key precursor for the formation of atmospheric secondary inorganic particles, such as ammonium nitrate and sulfate. Although the chemical processes associated with the gas-to-particle conversion...

• Implementation of an incoherent broadband cavity-enhanced absorption spectroscopy technique in an atmospheric simulation chamber for in situ NO.sub.3 monitoring: characterization and validation for kinetic studies.

  Authors:Axel Fouqueau, Manuela Cirtog, Mathieu Cazaunau, Edouard Pangui, Pascal Zapf, Guillaume Siour, et al.From:Atmospheric Measurement Techniques (Vol. 13, Issue 11) Peer-Reviewed

  Nov. 25, 2020274 words Brief article An incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) technique has been developed for the in situ monitoring of NO.sub.3 radicals at the parts per trillion level in the CSA simulation chamber (at...

• Evidence of the complexity of aerosol transport in the lower troposphere on the Namibian coast during AEROCLO-sA.
