      Holanda, Bruna A.; Franco, Marco A.; Walter, David; Artaxo, Paulo; Carbone, Samara; Cheng, Yafang; Chowdhury, Sourangsu; Ditas, Florian; Gysel-Beer, Martin; Klimach, Thomas; Kremper, Leslie A.; Krüger, Ovid O.; Lavric, Jost V.; Lelieveld, Jos; Ma, Chaoqun; Machado, Luiz A. T.; Modini, Robin L.; Morais, Fernando G.; Pozzer, Andrea; Saturno, Jorge; Su, Hang; Wendisch, Manfred; Wolff, Stefan; Pöhlker, Mira L.; Andreae, Meinrat O.; Pöschl, Ulrich; Pöhlker, Christopher (Peer reviewed; Journal article, 2023)
      Smoke from vegetation fires affects air quality, atmospheric cycling, and the climate in the Amazon rain forest. A major unknown has remained the quantity of long-range transported smoke from Africa in relation to local ...

    • Black carbon aerosol reductions during COVID-19 confinement quantified by aircraft measurements over Europe 

      Krüger, Ovid O.; Holanda, Bruna A.; Chowdhury, Sourangsu; Pozzer, Andrea; Walter, David; Pöhlker, Christopher; Hernández, Maria Dolores Andrés; Burrows, John P.; Voigt, Christiane; Lelieveld, Jos; Quaas, Johannes; Pöschl, Ulrich; Pöhlker, Mira L. (Peer reviewed; Journal article, 2022)
      The abrupt reduction in human activities during the first lockdown of the COVID-19 pandemic created unprecedented atmospheric conditions. To quantify the changes in lower tropospheric air pollution, we conducted the BLUESKY ...

    • A global review of the state of the evidence of household air pollution's contribution to ambient fine particulate matter and their related health impacts 

      Chowdhury, Sourangsu; Pillarisetti, Ajay; Oberholzer, Alicia; Jetter, James; Mitchell, John; Cappuccilli, Eva; Aamaas, Borgar; Aunan, Kristin; Pozzer, Andrea; Alexander, Donee (Peer reviewed; Journal article, 2023)
      Direct exposure to household fine particulate air pollution (HAP) associated with inefficient combustion of fuels (wood, charcoal, coal, crop residues, kerosene, etc.) for cooking, space-heating, and lighting is estimated ...

    • A machine learning examination of hydroxyl radical differences among model simulations for CCMI-1 

      Nicely, Julie M.; Duncan, Bryan; Hanisco, Thomas F.; Wolfe, Glenn M.; Salawitch, Ross J.; Deushi, Makoto; Haslerud, Amund Søvde; Jöckel, Patrick; Josse, Béatrice; Kinnison, Douglas E.; Klekociuk, Andrew; Manyin, Michael E.; Marécal, Virginie; Morgenstern, Olaf; Murray, Lee T.; Myhre, Gunnar; Oman, Luke D.; Pitari, Giovanni; Pozzer, Andrea; Quaglia, Ilaria; Revell, Laura E.; Rozanov, Eugene; Stenke, Andrea; Stone, Kane; Strahan, Susan E.; Tilmes, Simone; Tost, Holger; Westervelt, Daniel M.; Zeng, Guang (Journal article; Peer reviewed, 2020)
      The hydroxyl radical (OH) plays critical roles within the troposphere, such as determining the lifetime of methane (CH4), yet is challenging to model due to its fast cycling and dependence on a multitude of sources and ...

    • Numerical simulation and evaluation of global ultrafine particle concentrations at the Earth's surface 

      Kohl, Matthias; Lelieveld, Jos; Chowdhury, Sourangsu; Ehrhart, Sebastian; Sharma, Disha; Cheng, Yafang; Tripathi, Sachchida Nand; Sebastian, Mathew; Pandithurai, Govindan; Wang, Hongli; Pozzer, Andrea (Peer reviewed; Journal article, 2023)
      A new global dataset of annually averaged ultrafine particle (UFP) concentrations at the Earth's surface for the years 2015–2017 has been developed through numerical simulations using the ECHAM/MESSy Atmospheric Chemistry ...
