Infrasonic Observatory data from the NOAA Environmental Technology Laboratory
Entry ID: OAR0081

[ Update this Record ]

Summary
Abstract: The Infrasonic Observatory is an array of infrasonic microphones located at the
Boulder Atmospheric Observatory in Erie, Colorado. The array measures the
direction, pressure amplitude, elevation angle, power spectra, and duration of
infrasonic geoacoustic sound waves in a frequency range centered around 1 Hz.
The Infrasonic Observatory detects geoacoustic noise from various sources,
including severe weather, avalanches, earthquakes, volcanic eruptions,
explosions, and meteors. One year of the data from the Infrasonic Observatory
has been processed and analyzed for distribution. The remaining data is
archived on magnetic tape.
