Fluxgate magnetometers are an essential tool for solar-terrestrial research and monitoring or forecasting space weather. They provide high precision measurements of the Earth’s magnetic fields and can be used to infer the currents that transport energy and momentum through the magnetosphere and...

Samson, J. C., Rankin, Robert, Wei, C. Q., Frycz, P.
A three-dimensional compressible resistive magnetohydrodynamic simulation code, with inclusion of the fully generalized Ohm's law, has been developed to study the nonlinear evolution of field line resonances in Earth's magnetosphere. A simple Cartesian box model of an inhomogeneous plasma with...

Enhanced N2 and O2 densities inferred from EISCAT observations of Pc5 waves and associated electron precipitation
Download2016
Yau, Andrew W., Sydorenko, Dmytro, Rankin, Robert
An advanced two-dimensional numerical model of the coupled ionosphere and magnetosphere is used to analyze EISCAT observations of ULF waves that are accompanied by electron precipitation with a wide energy spectrum. The observations show columns of significantly enhanced electron density produced...

Identifying and analyzing spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981-2018.
DownloadSpring 2021
This study looked at the spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981 to 2018. Studying patterns of lightning fires over space and time can provide great insight into understanding, highlighting, and quantifying these sequences. This is of great...

Increasingly Parallel Pressure Anisotropic Ballooning Instability: A New Mechanism for Magnetospheric Substorm Onset
DownloadFall 2019
Geomagnetic substorms are a process through which energy stored in Earth’s magnetosphere is suddenly and violently released. On the ground, this process is largely observed as a vibrant and dancing display in the aurorae and is well documented, while the sequence of events that occurs in the...

The ionospheric Alfvén resonator (IAR) is an area of space that, due to sharp Alfvén speed gradients, has the ability to trap electromagnetic plasma wave energy, where it bounces in the Alfvén mode between near-Earth space and the lower ionosphere. Here we present research that, by comparing...

Lightning and fire characteristics within the Northwest Territories (NWT) jurisdiction of the Mackenzie Basin between 1994 and 1999 are examined using data from the lightning detection network operating in the NWT and from the national Large Fire Database maintained by the Canadian Forest...

Lightning is widely acknowledged as a major cause of wildland fires in Canada. On average, 250,000 cloud-to-ground lightning strikes occur in Alberta every year. Lightning-caused wildland fires in remote areas have considerably larger suppression costs and a much greater chance of escaping...
