Operation Notes: (may not be current)
This section summarizes major changes in equipment or in instrumentation at CVS.

  • 06/15/2004: BH channels sampling rate changed from 20 Hz to 40z.
  • 09/22/2003: Q4120 datalogger upgraded.
  • 07/01/2003: HH channels reconfigured to have casual filtering.
  • 03/06/2000: Newer version of MSHEAR installed as upgrade from older version.
  • 12/15/1999: Q4120 software upgraded to MSHEAR.
  • 04/30/1998: Station first operational around 23:30 GMT.
  • 04/24/1998: Kinemetrics FBA-23 strong-motion accelerometer selected.
  • 10/03/1997: Streckeisen STS-2 broadband seismometer, frame-relay access device, pressure/temperature sensors, and Quanterra Q4120 Datalogger installed.

Noise Characteristics:
The figures below are cumulative plots of power spectral density (psd) determined from the broadband channels. In each figure, the vertical component psd is plotted with blue diamonds, the north component psd with red squares, and the east component psd with green circles. The results are presented in the 5 different frequency bands, and the USGS/Albuquerque low noise model is plotted as a dashed line in each. The PSD units are in dB (decibel) relative to 1 (m/s**2)**2/Hz. The current annual plot is updated weekly.

Data Availability:
BDSN waveforms and associated metadata are available at the Northern California Earthquake Data Center (NCEDC).

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.

Help on using these tools is available.
