DATA APPLICATIONS

Application	Description
Australian Geomagnetic Reference Field Values Application	An application to calculate geomagnetic field values in Australia using the 2010 Australian Geomagnetic Reference Field model (AGRF) model.
Canberra Realtime Data Application	Canberra Realtime Data for last 24 hours
Minute Values Request Form Application	Minute Values Request Form
Australia-wide Total Intensity Variability Application	Using data from the six Australian continental magnetic observatories, a contour display of the rate-of-change of magnetic total intensity, F, over the continent is shown below. This provides a broad view of how F changes across Australia. The units shown on the contours are in nanoTesla per hour. The grey squares indicate the locations of the magnetic observatories. Both real-time and historic data can be displayed in this format. All maps are generated from a period of 15 minutes of observatory data and available at 15 minute intervals.
K Indices from Australia Application	The k index is a quasilogarithmic index of geomagnetic activity relative to an assumed quiet day curve for the recording site. k is a code from 0-9 that characterizes magnetic activity (0 being the least active field and 9 the most active field) over a 3 hour period.
International Quiet Days (IQD) and International Disturbed Days (IDD) Application	International Quiet Days (IQD's) are the days where the geomagnetic variations are a minimum in each month. International Disturbed Days (IDD's) are 5 days in each month where the geomagnetic variations are maximum. The classification of days is relative only to the month of calculation. The average disturbance level in one month may differ from another.
