2.2.2 spase://VMO/NumericalData/WDC/Apia/Magnetometer/PT1M/ASCII_FORMAT Apia Magnetometer 1-min Data in ASCII Flat Table Format 2012-05-02T12:34:56.789 Apia Magnetometer data, 1-min time resoluion, in ASCII format. Magnetic Field Vector Element List: DHXYZF. Note that the list of magnetic field elements that appear in the data set may change over the course of time. For instance, many stations have shifted from DHZ to the XYZ representation of the magnetic field. The time history listed below summarizes changes in element content. A description of the WDC Data Exchange Format for CADENCE magnetic field data is included at the end of this data product description.

If a gap is present at the beginning or end of the file, the time span start and stop dates could be inaccurate as they are assigned assuming an absence of such gaps. PT1M Earth.Surface ground station magnetometer magnetic field magnetogram Apia WDC Station Code: API 1-minute ASCII Flat File ASCII Flat Table Universal Time Time Time is expressed using a five column format with the following order: year, month, day, hour, and minute, each stored in interger format.
