Overview:

• Contributions to the geomagnetic disturbance field

• Description of the magnetospheric model

• Validation against observatory measurements

 

NGDC/USGS Real-time Calculator

Represented magnetospheric disturbance fields:

- Magnetospheric variations caused by space weather

- Rotation of the Earth in the magnetosphere

- Secondary magnetic fields of electric currents, induced by time-varying magnetic fields in the conducting Earth and oceans

 

USGS Dst Index

- Definitive Index for the past
      • Uses definitive (clean) magnetic field data
      • 25 year processing span

- Near Real-time Index
      • Uses preliminary (near real-time) magnetic field data
      • 5-15 minute latency

- USGS versus Kyoto Dst
      • Better time resolution (USGS: 1-minute, Kyoto: 1-hour)
