These data are the time series recorded by Geoscience Australia`s geomagnetic observatories in Australia and Antarctica. Australian observatories are located near Canberra (ACT), Charters Towers (Queensland), Alice Springs and Kakadu (NT), Gnangara and Learmonth (WA). Antarctic observatories are located at Macquarie Island, Mawson and Casey. The time series record the temporal variations of three components of the geomagnetic field and its total-field strength at each location. The rates at which the variations are recorded are once per second for the 3-component data and once every 10 seconds for the total-field data. These time series are also used to derive a range of subsidiary time series consisting of data samples at 1-hour, 1-day, 1-month and 1-year intervals. These data are calibrated by regular (usually weekly) absolute measurements of the magnetic field. These calibrations allow corrections to be made for instrument drift so that the long-term (annual, decadal) variations of the geomagnetic field can be tracked accurately.

Contains metadata and quality information on the Australian Regional GPS Network (ARGN), the South Pacific Regional GPS Network (SPRGN) and other permanent GPS stations across Australia, which are observed on a non continuous basis. Metadata information for each tracking stations contains data such as the site name, connection type, location, position, equipment and their serial numbers, main contact agencies, etc. The site quality database contains statistical quantities for each site for each day of year.

ADMAP is a Gridmerged compilation of over 700 individual survey TMI grids, with a cell size of approximately 80 m (in fact it is 0.00833333 degrees). The first preliminary grid at this resolution with data type IEEE4ByteReal has been further processed in the Fourier domain to produce a half vertical derivative grid, called "aust_18122007_008333_vd05.ers"

The first preliminary grid at this resolution with data type IEEE4ByteReal has been further processed to produce a grey-scale image (a one-band Unsigned8BitInteger byte file) of the 0.5 vertical derivative data.

The Landsat-7 picture Mosaic of Australia was produced as part of Geoscience Australia's 'Unlocking the Landsat Archive' Project. These images were primarily acquired in March 2010 ********** 07/08/15 After consulting with my manager we have decided that the product provided is incorrect and not supported by NEMO. Can you please remove the Landsat-7 Picture Mosaic Map of Australia from the website. Lien Lien Ly Team Leader - Product Generation | National Earth and Marine Observation Group
