Geomagnetic Absolute Mean Values at Hourly Intervals from 220 Observatories Worldwide
This file is comprised of absolute mean hourly values of the geomagnetic components
D, H and Z or X, Y and Z. These values, on magnetic tape, are available from approximately
220 of the 400 worldwide observatories which have ever operated. Most of the values
were hand-scaled from the analog recordings (magnetograms) and were added to the file
via punched cards. From some observations, for more recent years, there are means
of values recorded directly on
magnetic tape from digital magnetometers at various sample rates, for example, each minute. The accuracy of these data varies but is generally good, particularly for the more recent years. Approximately 60 observation-years of these data are added to the files each year.

Supplemental Information |
Observing station type: Geophysical Observatory. Data collection type: Network. Number
of sites: 200 observatories.Quality control: The accuracy of these data varies but
is generally good, particularly for the more recent years. Processing: Most of the
values were hand-scaled from the analog recordings (magnetograms). In more recent
years they include means of values recorded directly on magnetic tape from digital
magnetometers at various sample rates, for
example, each minute. |
