Optimizing PPP Performance by Incorporating ZWD Constraints Derived From Data Assimilation
Abstract One of the primary error sources limiting the performance of the Precise Point Positioning (PPP) technique is the atmospheric wet delay, caused by the presence of water vapor in the lower atmosphere. Accurately representing this parameter is crucial for improving the initialization and accuracy of satellite‐based positioning techniques ...

Inferring Long‐Term Geocenter Motion From Low‐Degree Gravity Field
Abstract Accurate determination of geocenter motion is essential not only for establishing a stable terrestrial reference frame, but also for deriving a complete picture of large‐scale global mass redistribution in the Earth system. For geophysical applications, reliable geocenter motions can be inferred from time‐variable gravity fields provided by ...

Abstract We investigate repeating earthquakes at Shishaldin Volcano (Alaska) by applying a multi‐stage clustering technique to the waveforms of approximately 330,000 Long‐Period (LP) earthquakes recorded between October 2003 and July 2004, a period that includes a minor eruption.

The Effect of Mars Impact Crater Topography on Seismic Signals
Abstract Meteorite impacts on Mars result in seismic recordings with relatively small surface wave amplitudes compared to body wave amplitudes, unlike what is generally observed in earthquakes. Here, we test with numerical modeling whether Mars' topography could be responsible for the preferential attenuation of surface waves. We use a spectral element

Mass Changes in a High‐Latitude River Basin From Two Decades of GRACE/GRACE‐FO
Abstract The rise in global temperatures is amplified in high‐latitude regions, where snow and ice play a vital role in the hydrological cycle. Understanding the impacts of climate change on ecosystems and communities in Northern regions requires accurate hydrological data.
