Not enough H₂O₂ to warm early Mars

Maxime Maurice, François Forget, Franck Lefèvre, Aurélien Stolzenbach, A. Yassin Jaziri, Ashwin S Braude, Martin Turbet, Ehouarn Millour, Yangcheng Luo

There exists strong geomorphological, sedimentary and mineralogical evidence that Mars had an active surface hydrological cycle during the Noachian period, about 3.8 Gyr ago (Ga). However, how surface temperatures compatible with perennial liquid water could be sustained in spite of a Sun that only…

Simultaneous estimation of radiance and its sensitivities to radiative properties in a spherical-heterogeneous atmospheric radiative transfer model by Monte Carlo method: Application to Titan

Zili He, Sandrine Vinatier, Vincent Eymet, Vincent Forest, Bruno Bézard, Pascal Rannou, Sébastien Rodriguez, Emmanuel Marcq, Richard Fournier, Stéphane Blanco, Nada Mourtaday, Yaniss Nyffenegger-Péré, Sébastien Lebonnois, Anni Määttänen

<div><p>We propose a control variates technique to reduce the variance of null-collision Monte Carlo algorithms used for solving the Radiative Transfer Equation (RTE) in highly heterogeneous media. The method complements the classical spatially partitioned overestimate approach by…

The biogenic sulfur cycle in the coupled ocean–sea ice–atmosphere system

Sakiko Ishino, Megan Willis, Hélène Angot, Thorsten Bartels-Rausch, Odile Crabeck, Bruno Delille, Erin Dunne, Emily Franklin, Antoine Haddon, Hakase Hayashida, Sankirna Joge, Rémy Lapere, Hyung-Gyu Lim, Anoop Mahajan, Marc Mallet, George Manville, Louis Marelle, Daiki Nomura, Kerri Pratt, Ilka Peeken, Ruth Price, Rafel Simó, Jacqueline Stefels, Jennie Thomas, Cort Zang, Nadja Steiner

Polar oceans and sea-ice regions are global hot spots for the production of biogenic volatile methylated sulfur (VMS) compounds: dimethyl sulfide (DMS) and methanethiol (MeSH). VMS compounds make important contributions to atmospheric particle formation and cloud property modulation, especially…
