  1. Infrasound in the Geosciences Milton Garces, University of Hawaii, Manoa Second NSF Infrasound Workshop, June 8, 2005

  2. Summary • Data dissemination – SEED format for archiving at IRIS. Metadata can be difficult to standardize. • Capability for real-time data streaming.Quality control is responsibility of the operator. • Sensor availability: Possibilities through PASSCAL, IRIS Consensus, Geoinfrastructure, MRI. • International collaborative effort – define project. Continental dynamics. • Large-scale arrays, 100’s of instruments. • Large ATM project, coordinate with NCAR. • Export controls on some specialized software. PMCC available for academic use. Matseis available. • GEOSS, products for society benefit.

  3. Domestic (US) involvement in GEOSS. • Infrasound as reliable technology. • Applications in civil defense (HS), natural hazards. • IMS data available from US, Canada, and Germany, soon UK. Two-day latency. Possibility for streaming. • More extensive use of IRIS microbarograph data. Sampled at 0.5 or 1 Hz. • Use of hydrophone data. • Multiple technology data for case studies. • Need better links to ATM and OCE programs. • Possible workshop on Atmospheric Tomography. • COV workshop in volcano-acoustic monitoring (01/06). • Produce workshop report.
