Chemical Tracers for 3D Atmospheric Asymmetries on WASP-69 b
The episode discusses a paper on WASP-69 b, a warm Saturn, using 3D climate and chemistry models. Hosts explain that methane traces deep latitudinal temperature variations, sulfur dioxide traces upper-atmosphere photochemistry and longitudinal asymmetry, while carbon dioxide reliably reflects bulk metallicity. They warn that 1D retrievals can mistake temperature-driven methane changes for carbon-rich composition.
