Given the current rapid development of the global infrasound network, there are exciting new research opportunities in many areas of infrasound, from array design to source identification to atmospheric profiling. To assist the scientific research community to exploit this new resource, the Geological Survey of Canada (www.seismo.nrcan.gc.ca) and the Royal Netherlands Meteorological Institute (www.knmi.nl) are developing an infrasound event archive.

The purpose of the archive is two-fold: first, to provide an open, unencumbered source of high-quality infrasound data for interested researches, and second to help raise the profile of infrasound amongst the acoustic, atmospheric and earth science research communities to encourage wider participation in infrasound studies.

Data will be accepted from any infrasound station operator who is prepared to make data freely available, and data will be organized by event as time series associated with relevant ancillary information such as station and source location information. The archive will be hosted at both the Geological Survey of Canada in Ottawa and at the Royal Dutch Meteorological Institute in De Bilt. Data will be made available to any interested researcher in a wide range of data formats including CSS3.0. Data access can be either interactive through a web interface or via AutoDRM. A prototype of the website is available at:
http://www.seismo.nrcan.gc.ca/nwfa/is_events/

This prototype is currently running only in Ottawa, and is currently populated only with data from the Canadian infrasound array at Lac du Bonnet, Manitoba.

Station operators interested in contributing data, and scientists interested in using data are encouraged to contact the authors at the above address.

Stand by for further developments!

GINA is made possible with support from the Nuclear Monitoring Project, Geological Survey of Canada and ORFEUS.
