Geomagnetism Data and Applications
- Real-time data from Canberra Observatory
A magnetogram showing how the magnetic field at the Canberra Magnetic Observatory has changed over the last 24 hours. Data for this display are updated every ten minutes.
- Australian Geomagnetic Reference Field (AGRF) Values
Calculate the magnetic declination or other magnetic field elements for any given geographic coordinates. The AGRF is a mathematical model of the geomagnetic field for the Australian region and is valid until 2010. The model is a useful tool for compass navigators such as bushwalkers, orienteers, mariners and pilots or anyone who needs to convert compass bearings to true bearings and those who need to know the magnitude or direction of the geomagnetic vector in the Australian region.
- Minute Values - Data and Plots
Select an observatory and time period, return the minute values as a plot or data file.
- Geomagnetic Data
Specify a time period and the application will return indices (k, aa, IQD/IDD).
