Spatially Resolved Infrared Observations of Saturn. 1. Equatorial Limb Scans at 20 μm
Abstract
Drift scans of the equator of Saturn have been obtained through narrow band filters at 17.8, 19.7, and 22.7 μm. Spatial resolution was ≃17% of the equatorial diameter. These observations clearly differentiate otherwise tenable atmospheric models. A published model by A. Tokunaga and R.D. Cess [ Icarus32, 321-327 (1977)] is shown to represent these new observations significantly better than other models from the literature.
