USGS-Dst Index
The USGS-Dst index is a global measure of low-latitude magnetic disturbance. It is used to define the phases of a geomagnetic storm. It is provided at a 1-minute time resolution in real-time and supports the operations of NOAA-Space Weather Prediction Center and the Air Force Research Lab.
Electric Field Estimates
Combining magnetic field measurements with local conductivity values, we estimate the electric field induced by rapid magnetic field changes. Using regional conductivity estimates, we are developing hazard maps based on these electric field calculations that indicate the threat of geomagnetically-induced currents.
Pulsation Indices
Using wavelet analysis to separate by frequency band, the pulsation indices are real-time specifications of Pc3, Pc4, and Pc5 waves. These indices require 1-second data to fully resolve the high-frequency components.
