Journal ArticleDOI
Enhanced role of transition metal ion catalysis during in-cloud oxidation of SO2.
Eliza Harris,Bärbel Sinha,Bärbel Sinha,Dominik van Pinxteren,Andreas Tilgner,Khanneh Wadinga Fomba,Johannes Schneider,Anja Roth,Thomas Gnauk,B. Fahlbusch,Stephan Mertes,Taehyoung Lee,Jeffrey L. Collett,Stephen F. Foley,Stephan Borrmann,Stephan Borrmann,Peter Hoppe,Hartmut Herrmann +17 more
TL;DR: It is found that sulfur dioxide oxidation catalyzed by natural transition metal ions is the dominant in-cloud oxidation pathway, and the sulfate produced will have a short lifetime and little direct or indirect climatic effect.
Journal ArticleDOI
Biogenic Potassium Salt Particles as Seeds for Secondary Organic Aerosol in the Amazon
Christopher Pöhlker,Kenia Teodoro Wiedemann,Kenia Teodoro Wiedemann,Kenia Teodoro Wiedemann,Bärbel Sinha,Manabu Shiraiwa,Sachin S. Gunthe,M. L. Smith,Hang Su,Paulo Artaxo,Qi Chen,Yafang Cheng,W. Elbert,Mary K. Gilles,A. L. D. Kilcoyne,Ryan C. Moffet,Ryan C. Moffet,Markus Weigand,Scot T. Martin,Ulrich Pöschl,Meinrat O. Andreae +20 more
TL;DR: It is suggested that the primary emission of biogenic salt particles directly influences the number concentration of cloud condensation nuclei and affects the microphysics of cloud formation and precipitation over the rainforest.
Journal ArticleDOI
Co-occurrence of denitrification and nitrogen fixation in a meromictic lake, Lake Cadagno (Switzerland)
Hannah Halm,Niculina Musat,Phyllis Lam,Rebecca Langlois,Florin Musat,Sandro Peduzzi,Gaute Lavik,Carsten J. Schubert,Bärbel Sinha,Julie LaRoche,Marcel M. M. Kuypers +10 more
TL;DR: The results show that N(2) fixation could partly compensate for the N loss and that both processes occur at the same locale at the the same time as suggested for the ancient Ocean.
Journal ArticleDOI
High-Precision Measurements of 33S and 34S Fractionation during SO2 Oxidation Reveal Causes of Seasonality in SO2 and Sulfate Isotopic Composition
TL;DR: Comparison of modeled seasonality with observations shows the TMI-catalyzed oxidation pathway is underestimated by more than an order of magnitude in all current atmospheric chemistry models.
Journal ArticleDOI
Siliceous deep-sea sponge Monorhaphis chuni: A potential paleoclimate archive in ancient animals
TL;DR: In this paper, the authors used the oxygen isotopic composition and Mg/Ca ratios determined along center-to-surface segments of a giant metazoan spicule collected in the East China Sea in a depth of 1110m.
