- This CD-ROM contains one-minute values of geomagnetic data
- from all magnetic observatories of the USGS network for the
- years 1985-1989. The one-minute values are provided as
- 3-component vector data (Horizontal Intensity, Vertical
- Intensity, and Declination) from a fluxgate magnetometer,
- as well as scalar data (Total Intensity) from a proton
- precession magnetometer. The database contains geomagnetic
- values for two of the largest magnetic storms ever recorded.
- The capability also exists to write data files from the
- CD-ROM to a hard drive or floppy disk in NGIC or World Data
- Center-A ASCII formats.
