Abstract In this paper we present an efficient mode-matching technique to analyze tilted-coil antennas in anisotropic geophysical formations. In this problem, a number of coil antennas with arbitrary relative tilt angle ...

Abstract Optical methods deployed for studying motion and deformation of objects often struggle to distinguish small displacements hidden behind observational noise. In geophysical applications, this has limited analysis...

The problem of determining the source has been analyzed during the last years in different areas of ap plied mathematics and has received considerable attention in many current research, as it has applications in fields ...

Subsurface temperature uncertainty represents a major risk in geothermal drilling, particularly in volcanic systems where permeability, lithology, and fluid circulation create highly heterogeneous thermal regimes. This s...

BackgroundIn the field of geological exploration of coal mines, methods such as in-seam seismic exploration, the transient electromagnetic method, and audio-frequency electrical penetration offer unique technical advanta...

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission will advance global soil moisture monitoring through high-resolution L-band observations. However, accurate fine-scale retrieval remains challenging due to the 12-da...

Abstract Substorms are known to induce global magnetosphere‐ionosphere coupling. However, the specific response of the dayside ionospheric electric field and its influence on the equatorial electrojet (EEJ) remain cont...

Abstract Magnetic reconnection hosts regions of enhanced temperature anisotropy that could excite various kinetic instabilities and waves. However, the relation between electron firehose instability and the leading edge ...

Abstract We have executed a series of simulations with the NASA Ames Mars Global Climate Model by systematically increasing horizontal and vertical resolution with the goal of resolving small‐scale waves that significa...

Abstract Inverse energy cascade (IEC), where energy moves from small to large eddies, has been debated, with limited observational evidence. This study used 19 months of Doppler Lidar data from Qingdao, China, to examin...

Abstract Marine magnetic anomalies are pivotal to our understanding of plate tectonics, geomagnetic fields, and deep Earth dynamics. However, the question of how Ti‐rich titanomagnetites, the primary remanence carriers...

Abstract The seismic velocity structure beneath East Africa suggests interconnected corridors of hot mantle are upwelling beneath the continent. However, the geochemical evidence for deep mantle in Ethiopia‐Kenya‐Tan...

Abstract This study investigates the F‐region plasma density and irregularities response during the May‐2024 storm using Swarm and Gravity Recovery and Climate Experiment Follow‐On (GRACE‐FO) data. Swarm‐B prov...

Abstract Ultra‐low frequency (ULF) waves in the Pc5 band are essential for the transport of electrons in the radiation belt and the transport of energy from the solar wind into the magnetosphere. Based on ∼14‐year ...

Abstract Developing AI models that match or exceed the forecast skill of numerical weather prediction (NWP) systems but run much more quickly is a burgeoning area of research. Most AI‐NWP models, however, have been tra...

We present the Met Office Hadley Centre's sea ice and sea surface temperature (SST) data set, HadISST1, and the nighttime marine air temperature (NMAT) data set, HadMAT1. HadISST1 replaces the global sea ice and sea surf...
