Status of USGS Geomagnetism Observatories
Carol A. Finn and Alan M. Berarducci
Introduction The U.S. Geological Survey (USGS)
Geomagnetism Program currently operates 14
magnetic observatories across the United States
and its territories and covering a wide range of
latitude and longitude. Current efforts are
focused on improving operational baseline
stability through increased monitoring and
through facility improvements.

• Data Acquisition
• and Transmission Improvements
• Utilizing magworm software to record and
  transmit 1-min data in realtime over the Internet
• Implemented backup capability via ftp for Air
  Force Weather Agency (AFWA) operations
• Implemented automatic fail-over from
  GOES-transmitted data to Internet-transmitted
  data
• Improved capacity and reliability of magworm
  buffers to minimize data losses due to comm
  interruptions
• A Geomag DevLab was established behind ANSS
  firewall for improved security protections and to
  isolate development from operations
• USGS observatory data files now being
  transmitted to INTERMAGNET web site every 12
  minutes

• Baseline Improvements
• Slow progress is being made in improving
  observatory baselines two examples shown below
