  • 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.

  • 2022 Definitive 1-minute Scott Base (SBA) data is continuous 1-second data recorded by New Zealand's Geomagnetic Observatories SBA in 2022 that was processed at 1-minute sampling, cleaned (spikes removed) and baseline (absolute values) corrected following INTERMAGNET guidelines. The data was submitted to INTERMAGNET in May 2023 and passed the INTERMAGNET reviewing process. DOI https://doi.org/10.21420/axhk-e303 Cite as: Thornton, M., Goodyear, G., Shaw, S.

  • 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.
