Fig. 4


PACS (top) and HIFI (bottom left) observations of Neptune compared to models with varying mid-stratospheric CH4 mixing ratios. Bottom right panel: atmospheric model. Solid lines: temperature (black) and CH4 (blue) profiles. Dashed lines: contribution functions for the CH4J = 6–5 1882.0 GHz line (at HIFI resolution) and for the J = 6–5 (159.3 μm) and J = 8–7 (119.6 μm) multiplets (at PACS resolution).
