The IMS Infrasound Network: Current Status and Technological Developments

  • Chapter
  • First Online:
Infrasound Monitoring for Atmospheric Studies

Abstract

The International Monitoring System (IMS) comprises 337 globally distributed facilities for seismic, hydroacoustic, infrasound, and radionuclide monitoring. This chapter focuses on the infrasound component of the IMS, often referred to as the IMS infrasound network. The chapter begins with an overview of the network and of the main challenges associated with its establishment, sustainability, and detection capability. It follows with a general description of IMS stations as well as with a review of the latest advances in array geometry, wind-noise reduction systems, infrasound sensors, calibration, meteorological data, data acquisition systems, and station infrastructure. This chapter is intended for researchers and engineers who are interested in the specifications, design, status, and overall capabilities of the IMS infrasound network or in the construction of state-of-the-art infrasound stations.
