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 ...

First Coincident Radar and Optical Observations of a Meteor Radio Afterglow
Abstract It has been hypothesized that Meteor Radio Afterglows (MRAs) occur due to resonant transition radiation (RTR) where suprathermal electrons emit as they pass through electron density inhomogeneities in a turbulent plasma. Meteor trails are thought to produce suprathermal electrons through anion oxidation, which can be identified through meteor ...

Modeling the Deformation Response to Mt. Etna Sliding Flank
Abstract The southeastern flank of Mt. Etna volcano slides into the Ionian Sea at rates of centimeters per year. While gravitational spreading and tectonic forces can cause volcanic flank collapse, their effects intrinsically trade off with magmatic forcing. There is still strong uncertainty regarding the processes underlying the sliding.

Abstract The unexpected collapse of the Marmolada Glacier in the Italian Alps on 3 July 2022, caused 11 fatalities and emphasized the need for a deeper understanding of unstable glaciers. In response, we initiated a radar monitoring campaign to assess the stability of the remaining ice cliff and obtained a near‐continuous data set of displacement at ...

Calibration techniques of interferometric microwave receivers
An interferometer for orbital determination receives a satellite signal at different spatial points using antennas that form a baseline. Those received signals have a different phase which is related to the distance between the receiver antenna and the satellite and correlating those signals it is possible to get a very precise location of the ...

Monitoring Flood Inundation Dynamics From Space
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Abstract Arctic lake, bay and lagoon ice regimes play a crucial role in understanding permafrost stability, hydrology, and carbon cycling in permafrost regions. This study integrates field and Synthetic Aperture Radar (SAR) data from Sentinel‐1 to improve the classification of Arctic lake, bay and lagoon ice regimes, with a particular focus on the ...
