Scanned Mundaring ionospheric data and Gnangara magnetograms data

The scanned Mundaring ionospheric and magnetograms data file is about 640GB. The Mundaring ionospheric data have been available in the WDC Ionospheric page. The disk that contains all the scanned data from microfilms is archived in the SWS WDC store room. If you are interested in Gnangara or other stations magnetograms data, please check GA scanned data list first, which lists all availablle stations, year-month and datasets. And then contact us via
