Photometric Comparison of Metis and LASCO-C2 Polarized Brightness Images

Alberto Vásquez, Federico Nuevo, Aleksandr Burtovoi, Philippe Lamy, Marco Romoli, Hugo Gilardy, Richard Frazin, Nishtha Sachdeva, Ward Manchester Iv, Lucia Abbo, Yara de Leo, Federica Frassati, Giovanna Jerse, Federico Landini, Giuliana Russano, Clementina Sasso, Roberto Susino, Michela Uslenghi

The Metis coronagraph onboard Solar Orbiter and the LASCO-C2 coronagraph onboard SoHO both acquire white light polarized brightness (pB) images of the solar corona. When the Sun–Solar Orbiter distance is less than 0.85 AU, i.e., outside orbital segments around aphelia, the range of elongations…

Impact of Convectively Coupled Tropical Waves on the composition and vertical structure of the atmosphere above Cabo Verde in September 2021 during the CADDIWA campaign

Tanguy Jonville, Maurus Borne, Cyrille Flamant, Juan Cuesta, Olivier Bock, Pierre Bosser, Christophe Lavaysse, Andreas Fink, Peter Knippertz

In summer, Mixed Rossby Gravity Waves/Tropical Disturbances (MRG-TD) are known to drive intraseasonal humidity variability in the northeastern Atlantic troposphere, modulated by Equatorial Rossby (ER) and Kelvin waves. However, their impact on dust remains poorly understood, and MRG-TD tracks are…

Vertical and horizontal variability and representativeness of the water vapor isotope composition in the lower troposphere: insight from Ultralight Aircraft flights in southern France during summer 2021

Daniele Zannoni, Hans Christian Steen-Larsen, Harald Sodemann, Iris Thurnherr, Cyrille Flamant, Patrick Chazette, Julien Totems, Martin Werner, Myriam Raybaut

The isotopic composition of water vapor is a valuable tool to track atmospheric hydrological processes and to evaluate numerical models simulating the water cycle. To ensure accurate model-observation comparisons, understanding the spatial and temporal distribution of water vapor isotopes in the…

Night O₂ (a¹Δ_g) airglow spatial distribution and temporal behavior on Venus based on SPICAV IR/VEx nadir dataset

Daria Evdokimova, A. Fedorova, M. Zharikova, Franck Montmessin, O. Korablev, L. Soret, D. Gorinov, D. Belyaev, Jean-Loup Bertaux

The infrared O2 (a1Δg) airglow driven by the subsolar to antisolar circulation occurs between two global circulation regimes on Venus: the zonal super-rotation below 90 km and the subsolar to antisolar circulation over 120 km. Here we report the complete global results of SPICAV IR/Venus Express…
