    • Bradys Hot Springs Ambient Noise Correlation Functions (Initial Waveforms)

    Metadata Updated: January 20, 2025

    These files are ambient noise correlation (ANC) functions calculated for 11 days of continuous seismic data recorded by the Lawrence Berkeley network in the Brady geothermal field. These are SAC formatted seismic waveforms. The stations included are BPB04, BPB05, BPB07, BPB08, BPRT1, BPRT2, BPRT3, BPRT5, BRB10, BRP01, BRP02, BRP03, BRP04, BPR06, and BRP09

    The original data were cut into hour long traces and processed by differentiating, removing the mean, removing the trend, applying a 1% taper, whitening, removing the mean and trend again, and converting to single bit traces.

    The data were then correlated with those from other stations and stacked. The resulting files were then named according to the convention:

    STA1.STA2.CHAN1_CHAN2.NHOURS.stacked.sac

    The days included are from records during 2013 (julian days, 200,220-229).

    The ANC correlations were calculated on the raw data traces (without instrument corrections applied) to assess the quality of the signal as a function of frequency throughout the network. The data were recorded at 500 Hz. We observe high quality signals 30 Hz on all traces, and measurable signal up to 80 Hz on a subset of the traces.
