  • The dataset is composed of the original sheets on which the fields were recorded by light on photographic paper. Each sheet holds 24 hours of three recorded magnetic field components. Most of the components were labelled XYZ; some were labelled DHZ (e.g. 1991 magnetograms), and others were not labelled at all (e.g. 1966 magnetograms).

  • Preliminary 1-second and 1-minute Scott Base (SBA) data are submitted to INTERMAGNET in a standardized file format (IAGA-2002) every hour. The data can be downloaded via a free web access provided by INTERMAGNET at http://www.intermagnet.org/data-donnee/download-eng.php (Data Type: ‘provisional’). 1-minute (Sample Rate: ‘minute’) ‘provisional’ SBA data are available since 1996. 1-second data (Sample Rate: ‘second’) ‘provisional’ SBA data are available since 2012.

  • Continuous data recorded by New Zealand's Geomagnetic Observatories EYR, SBA & API, processed at 1-minute and 1-second sampling, and submitted to INTERMAGNET in a standardized file format (IAGA-2002) every hour. The data are preliminary as they are submitted without being cleaned (spikes removed) and baseline (absolute values) corrected. The preliminary 1-minute data are more timely and potentially more complete than the definitive 1-minute data, whereas the 1-minute definitive data goes through a data quality reviewing process with data recorded in one year not being published until the following year. There are no 1-second definitive data being produced. The data can be downloaded via a free web access provided by INTERMAGNET at http://www.intermagnet.org/data-donnee/download-eng.php (Data Type: ‘provisional’). 1-minute data (Sample Rate: ‘minute’): EYR available since 1994, SBA since 1996, and API since 1999. 1-second data (Sample Rate: ‘second’): EYR data available since 2012, SBA since 2012, and API since 2012.

  • Preliminary 1-second and 1-minute Eyrewell (EYR) data are submitted to INTERMAGNET in a standardized file format (IAGA-2002) every hour. The data can be downloaded via a free web access provided by INTERMAGNET at http://www.intermagnet.org/data-donnee/download-eng.php (Data Type: ‘provisional’). 1-minute (Sample Rate: ‘minute’) ‘provisional’ EYR data are available since 1994. 1-second data (Sample Rate: ‘second’) ‘provisional’ EYR data are available since 2012.

  • Continuous data recorded by New Zealand's Geomagnetic Observatories EYR processed at 1-minute sampling and baseline (absolute values) corrected. The data is being submitted to INTERMAGNET annually (submitted by July 1st for the previous year’s data Jan 1 to 31 Dec). EYR data since 1-Jan-1994 Before the definitive data for each year is being published via INTERMAGNET an international multi-step reviewing process is being applied to ensure international standards are being met.
