Residual Study: Testing Jupiter Atmosphere Models Against Juno MWR Observations
Abstract
The Juno spacecraft successfully traveled inside the radiation belt and the onboard Microwave Radiometer (MWR) measured Jupiter thermal radiation at wavelengths up to 50 cm, which penetrates the atmosphere down to a depth of a few hundred bars. The mission provides the first measurements of Jupiter's deep atmosphere, constraining the vertical distribution of its constituents. A crucial step in the validation process of each proposed atmospheric model is its comparison with the MWR data. Taking into account the complex MWR beam patterns and observation geometries, we present a residual study, testing multiple Jupiter input models against MWR data. We also present an extension of the study that iteratively improves the input model and generates Jupiter maps which best match the MWR data. A feature of our north-to-south scanning approach is that latitudinal structure is easily obtained relative to longitudinal, and the creation of optimum two-dimensional maps is addressed in this approach.
