Contribution to the gravity harmonics from the deep atmospheric flow. Shown are the solutions for the cloud-level wind (a), the radial decay profile (b), and the wind-induced even gravity harmonics (c-f). The grey lines and dots show all of the 3000 cases, and the black lines and dots show the plausible solutions. The red line in (a) shows the observed cloud-level wind, and the green line in (b) shows the solution in Kaspi et al. (2018). The red crosses in (e-f) show the expected mean value of the differential contribution.
