The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

DOPPLER STATION FOR ORBITAL TRACKING OF LOW-ORBIT SPACECRAFTS BY THEIR RADIO BEACON SIGNALS
Odessa Astronomical Publications, 2018 A ground station of orbital tracking of low-orbit spacecrafts has been developed and tested in the RI "Mykolaiv Astronomical Observatory". The station uses the Doppler shift of frequencies of signals radiated by spacecraft radio beacons for their orbital

Peering Inside Tropical Cyclones With the WIVERN Space‐Borne Doppler Radar
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract The WIVERN (Wind Velocity Radar Nephoscope) mission significantly enhances the global tropical cyclone observing system. Operating from a 500 km near‐polar orbit, the 3 m diameter conically scanning antenna provides an 800 km swath. The radar operated at 94 GHz (3 mm wavelength) provides high‐resolution observations with a vertical resolution ...

Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract If a spacecraft loses contact with Earth, ground‐based observatories can collect observations to assist the recovery effort by providing information on spacecraft location and state. Optical observations converted to a light curve of spacecraft magnitude over time show the spin period and/or orientation of the spacecraft.

Magnetic‐A: The New R‐Based Toolbox for Analysis of Paleomagnetic Data
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract Paleomagnetic remanence in rocks and sediments provides a unique means to constrain stratigraphic records in both space and time. This is because of the symmetry of the paleomagnetic field with respect to Earth's spin axis over geological time, and the global synchronicity of magnetic field reversals.

A Deep Learning Framework for Extreme Storm Surge Modeling Under Future Climate Scenarios
Earth's Future, Volume 14, Issue 3, March 2026.Abstract Coastal regions are increasingly exposed to sea‐level rise and intensifying storm surges, underscoring the urgent need for accurate long‐term predictions of extreme water levels to support robust adaptation planning. Physics‐based hydrodynamic storm surge models remain the gold standard for such projections, but are computationally demanding ...

Reconstruction of Core‐Surface Flows During the Last 3,300 Years
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Understanding the Earth's magnetic field evolution requires examining the fluid flow at the core‐mantle boundary that drives the changes over different timescales. The inversion process to derive core‐surface flow velocities from secular variation data encounters non‐uniqueness issues, necessitating a priori assumptions that yield different ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Grande Comore, the westernmost island within the Madagascar Comoros Volcanic (MCV) chain, hosts two juxtaposed basaltic volcanoes, Karthala and La Grille, with contrasting lava geochemical signatures and eruption frequencies. Their formation and dynamics have been explained either by a mantle plume or, more recently, as part of a ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Simultaneous analyses of complementary GNSS and InSAR measurements may lead to breakthroughs in our understanding of crustal deformation. We present an algorithm that combines InSAR with GNSS measurements, in which the GNSS data can be used either as original station velocities or as an interpolated and smoothed velocity field, to estimate ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The Tulu Moye geothermal field in the actively deforming Main Ethiopian Rift presents substantial potential for renewable energy production, where interactions between fault systems, hydrothermal fluids, and tectonic activity require careful management for sustainable development. Here we present a first‐order assessment of fault stability and
