Summary
The USGS Geomagnetism Program operates a network of magnetic observatories that collect vector and scalar magnetometer data for use in Earth main-field modeling, geophysics research, space physics research, and space weather hazard assessment and mitigation. Until mid-2011, only 1-minute time resolution magnetic field measurements were archived with the INTERMAGNET consortium following international magnetic observatory standards. 1-second time resolution magnetic field measurements, which had already been collected by all the USGS observatories for up to almost a decade prior, started being archived with INTERMAGNET on June 13, 2011, or July 27, 2012 in the case of the more recently constructed Deadhorse (DED) magnetic observatory.

This data release contains 1-second time resolution magnetic field measurements collected up through the end of 2012, after which time 1-second data from USGS magnetic observatories may be obtained from INTERMAGNET. There is some overlap between data in this release and those data archived with INTERMAGNET. Any discrepancies that may exist between these two data sources should resolve in favor of INTERMAGNET.
GUA-specific notes:
- some filenames originally and mistakenly identified the Guam observatory as "GUM", not "GUA"
- some filenames originally possessed with a ".sec" extension and were renamed to ".raw"

Purpose
These data are appropriate for geophysical research, space physics research, and space weather hazard assessment and mitigation. They are not fully calibrated, nor have they been checked for anomalies, and are therefore not appropriate for applications with absolute accuracy requirements, like Earth main-field modeling.
These data were collected from the USGS' magnetic observatory near Dededo, Guam, using the USGS' personal computer data collection platform (PCDCP) system.
