Optimal Wavelengths for Studying Thermal Emission from Active Volcanoes
Introduction: Our goal is to identify the optimal wavelengths for studying volcanic activity on Io. While better temporal, spatial, and spectral resolution is always desired, practical limitations lead one to limit both the wavelength range and spectral resolution of an observation. Our primary motivation is to assist the development of future spacecraft observations, but these results are also...
متن کاملModels for the Crustal Structure of Io: Implications for Magma Dynamics. W
Introduction: Io, the innermost of the Galilean satellites, is the most volcanically active body in our solar system. While its volcanic eruptions can be studied directly, our knowledge of the underlying magmatic processes rests wholly on indirect inferences. Here we combine constraints from magma ascent and crustal density models to gain insight into the plumbing system underlying the Promethe...
متن کاملIo volcanism seen by new horizons: a major eruption of the Tvashtar volcano.
Jupiter's moon Io is known to host active volcanoes. In February and March 2007, the New Horizons spacecraft obtained a global snapshot of Io's volcanism. A 350-kilometer-high volcanic plume was seen to emanate from the Tvashtar volcano (62 degrees N, 122 degrees W), and its motion was observed. The plume's morphology and dynamics support nonballistic models of large Io plumes and also suggest ...
متن کاملOptimization of energy window and evaluation of scatter compensation methods in myocardial perfusion SPECT using the ideal observer with and without model mismatch and an anthropomorphic model observer.
We used the ideal observer (IO) and IO with model mismatch (IO-MM) applied in the projection domain and an anthropomorphic channelized Hotelling observer (CHO) applied to reconstructed images to optimize the acquisition energy window width and to evaluate various scatter compensation methods in the context of a myocardial perfusion single-photon emission computed tomography (SPECT) defect detec...
متن کاملSpacecraft and In-situ Observations of the Mt. Erebus, Antarctica, Lava Lake: a Terrestrial Analogue for Pele on Io
Introduction: We have obtained multiple contemporaneous ground and space-based visible and hyperspectral infrared observations of a persistent active lava lake, one of the rarest volcanonological phenomenon. This unique dataset advances our understanding of remote sensing of lava lake activity on Earth and Io. The Mt. Erebus lava lake: Active lava lakes are the top of an open magma system and p...
