Estimating the Ionospheric Induction Electric Field using Ground Magnetometers
The ionospheric convection electric field is often assumed to be a potential field. This assumption is not always valid, especially when the ionosphere changes on short time scale…
Propagation of Slow Slip Events on Rough Faults: Clustering, Back Propagation, and Re-rupturing
Seismic and geodetic observations show that slow slip events (SSEs) in subduction zones can happen at all temporal and spatial scales and propagate at various velocities. Observat…

We report the characterisation of anthropogenic magnetic particulate matter (MPM) collected on leaves from roadside Callistemon trees from Lahore, Pakistan, and on known sources o…
Detecting Seismic Events with Computer Vision: Applications for Fiber-Optic Sensing
Seismologists working with fiber-optic sensing, commonly referred to as Distributed Acoustic Sensing (DAS), have yet to find an established way of automatically detecting signals …
Co-Production of a 10-m Cropland Extent Map for Continental Africa using Sentinel-2, Cloud Computing, and the Open-Data…
A central focus for governing bodies in Africa is the need to secure the necessary food sources to support their populations. It has been estimated that the current production of …
The energetic electron population dynamics at Jupiter, Saturn, Uranus and Neptune as revealed by historical spacecraft …
We review the mechanisms that shape the spatial distributions of energetic electrons trapped in the magnetospheres of Jupiter, Saturn, Uranus and Neptune. To determine what contro…
