Magnetic Field Vector Element List: HXYZF. 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 1-hr magnetic field data is included at the end of this data product description.

The values are in tenth-minutes for D and I, and in nanoTeslas for the intensity elements. The first hourly mean value represents the mean value between 00:00 UT and 01:00 UT, ..., the 24th value represents the mean between 23:00 UT and 24:00 UT. A missing value is identified by 9999. 117-120 I4 Daily Mean If any of the hourly mean values for the day are missing 9999 will appear as the daily mean. 121-122 Record end marker Two chars "cr"= 13 and "nl"= 10. The tabular bases, hourly mean values and daily means are right adjusted and signed if negative. Negative values are identified with a minus sign either adjacent to the first significant digit or in the high-order position of the field. Note: A blank digit will not appear between a (-) sign and the first significant digit. For example, a value may appear as -050 or b-50 but not as -b50 (b=blank). The 25 values in positions 21-120 will have the range -999 to 9998, with 9999 reserved for missing values. The records are sorted according to observatory code, year, month, element, day (positions 1-10). For the intensity elements: hourly value (nanoTeslas) = tab.base*100 + tab.value For the angles D and I: hourly value (Degrees) = tab.base + tab.value/600
