Australia-Wide Total Intensity Variability
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.
