Homestake Meeting Minutes, 07/27/17

Attending: Pat, Andrew, Daniel, Ross, Victor, Vuk

Agenda:

• Next Meeting: ???
• Data analysis topics
  • Data corrections, frame production (Gary/Daniel/Pat)
    • Pat: Frames ready at Caltech.
    • Daniel: Some timing hiccups, especially when a station is reset, timing off by 1/4 of a second. Have to chase it further, may be ignorable. Doesn't happen often. We could flag the times/stations when this happens.
    • Don't know if IRIS updated the data yet, should check with Gary…
  • Event catalog (Gary/Ross)
  • Radiometer updates (Pat, Andrew)
  • Parameter estimation for Rayleigh and Love (Pat) - pdf
  • Teleseismic events and Wiener filtering (Daniel, Michael)
  • Very-long-periods (Ross) - pdf, pptx
  • Velocity from noise correlations (Daniel): pdf

• Papers
  • Homestake Array Summary paper: pdf
    • Leads: Vuk, Gary, Victor
    • target: Seism. Research Lett., 6000 words, 10 figures.

• Active excitation overview paper
  • Leads: Gary, Ross
  • Others: Victor, Daniel,…
  • Will discuss at the next call.

• Surface Active Excitation
  • Leads: Victor, Boise
  • Others: Gary, Ross
  • Victor to talk to Lee about it.

• Underground Active Excitation:
  • Lead: Gary, Ross

• Parameter estimation for the Rayleigh and Love eigenfunctions (amplitude vs depth dependence).
  • Leads: Pat, Daniel
  • Also contributing: Victor, Vuk, Levi
  • Novel, but maybe insufficient for a publication. Could use the eigenfunction measurement for Rayleigh and assume something about Rayleigh field to make preliminary estimates of the Newtonian noise.

• Estimating directional and modal composition of the seismic noise. (Pat, Levi, Vuk)
  • Leads: Pat, Vuk, Levi

• Wiener filter application
  • Leads: Jan, Michael
  • Aim for late August.

• Teleseismic EQs and near-surface scattering
  • Leads: Daniel, Victor

• Time-variable velocity changes
  • Lead: Victor, not started yet

• Very low frequency harmonics (Ross)
