Remote Sensing, 2020 From 2002 to 2017, the Gravity Recovery and Climate Experiment (GRACE) mission’s twin satellites measured variations in the mass redistribution of Earth’s superficial fluids, which disturb polar motion (PM).

Concept and Design of Martian Far-IR ORE Spectrometer (MIRORES)
Remote Sensing, 2022 Sulfide ores are a major source of noble (Au, Ag, and Pt) and base (Cu, Pb, Zn, Sn, Co, Ni, etc.) metals and will, therefore, be vital for the self-sustainment of future Mars colonies. Martian meteorites are rich in sulfides, which is reflected in recent

Voyager 2 observation of the multifractal spectrum in the heliosphere and the heliosheath [PDF]
Nonlinear Processes in Geophysics, 2013 We look in detail at the multifractal scaling of the fluctuations in the interplanetary magnetic field strength as measured onboard Voyager 2 in the entire heliosphere and even in the heliosheath.

Constructing the space of valuations of a quasi-Polish space as a space of ideals
CoRR, 2021 We construct the space of valuations on a quasi-Polish space in terms of the characterization of quasi-Polish spaces as spaces of ideals of a countable transitive relation. Our construction is closely related to domain theoretical work on the probabilistic powerdomain, and helps illustrate the connections between domain theory and quasi-Polish spaces ...

Dispersion analysis of spaced antenna scintillation measurement [PDF]
Annales Geophysicae, 2009 We present a dispersion analysis of the phase of GPS signals received at high latitude. Basic theoretical aspects for spectral analysis of two-point measurement are given.

Annals of Pure and Applied Logic, 2013 We investigate some basic descriptive set theory for countably based completely quasi-metrizable topological spaces, which we refer to as quasi-Polish spaces. These spaces naturally generalize much of the classical descriptive set theory of Polish spaces to the non-Hausdorff setting.

Dimensionsgrad for locally connected Polish spaces [PDF]
Fundamenta Mathematicae, 2000 All spaces under discussion are separable and metrizable. Let \(A\) and \(B\) be disjoint subsets of a space \(X\). A closed set \(S\subseteq X\) is said to be a partition in \(X\) between \(A\) and \(B\) if there are open sets \(U\) and \(V\) in \(X\) such that \(A\subseteq U\), \(B\subseteq V\), \(X\smallsetminus S= U\cup V\), and \(U\cap V=\emptyset\

Remote Sensing, 2019 This study evaluates the gravity field solutions based on high-low satellite-to-satellite tracking (hl-SST) of low-Earth-orbit (LEO) satellites: GRACE, Swarm, TerraSAR-X, TanDEM-X, MetOp-A, MetOp-B, and Jason 2, by converting them into hydrological polar
