Maintenance Notice

On Friday, 03/01/2024, the main CCMC website and all CCMC applications will be intermittently unavailable between 7 AM to 11 AM Eastern Time.  The main CCMC website and all CCMC services/applications (e.g., iSWA, Runs-On-Request (ROR), Instant-Run, online visualization services, all Scoreboards, DONKI, CAMEL, StereoCAT, etc.) will be impacted.

Please refrain from submitting run requests via ROR during the maintenance window.

CalcDeltaB

Version: 2018

Postprocessing tool written in IDL to calculate Biot-Savart sums over magnetosphere, field-aligned currents and ionosphere height-integrated currents to determine magnetic perturbation at any location on the ground.

Caveats:

Magnetic perturbations do not include induction due to ground conductivities. The CalcDeltaB tool runs on output files sets for a single time step at a time and has no built-in time advance. Time variations are following the global magnetosphere simulation.

Inputs

Three-dimensional Magnetosphere model output files from OpenGGCM, SWMF, LFM or GUMICS, together with ionosphere electrodynamics outputs for matching times.

Outputs

ASCII files of magnetic perturbations (east, north, down component) at a grid of longitudes and latitudes.

Domains

  • Geospace

Space Weather Impacts

  • Geomagnetically induced currents - GICs (electric power systems)

Code Languages: IDL
