  14. NEIC Internal: QA/QC Real-time Probabilistic Ambient Noise Estimates Numerous artifacts are observed and identifiable. Strong signals are generated from instrumentation and telemetry issues such as calibration pulses, automatic mass re-centering and dropped packets. Mass re-center Calibration Dropped Packets Sensor Problem 10192 individual PSDs, binned in 1/8 octave intervals, are used to construct a Seismic Noise Probability Density Function for JFWS BHZ, shown to the right. 09/2000-02/2003.

  15. NEIC Internal: QA/QC Real-time Probabilistic Ambient Noise Estimates Significant noise at 0.1s (10Hz) due to the proximity to a road. 2370 individual PSDs, binned in 1/8 octave intervals, are used to construct a Seismic Noise Probability Density Function for HLID BHZ, shown to the right.
