Continuous automatic processing of the data is being performed at the French NDC from a number of IMS‐type infrasound stations in order to detect and characterize coherent infrasonic waves recorded on the arrays. A large number of detections are associated with natural phenomena. Infrasonic waves generated by strong earthquakes occurring within region of high mountains are of great interest. Such events allow the evaluation of the relative contributions of the different source mechanisms involved in large earthquakes, and offer an opportunity to improve our understanding of the amplification of ground displacement caused by the topography. Microbaroms as well as mountain waves are quasipermanent sources of infrasonic waves detected on a global scale. Their monitoring reveals clear periodic trends in the detected bearings and signal amplitude, providing further confirmation that long‐range propagation strongly depends on the atmospheric conditions. Signals from volcanic activities also offer a unique opportunity for atmospheric studies. At large propagation ranges from the volcanoes, infrasound measurements can be used as input of inversion procedures to evaluate more precisely the vertical structure of the wind in a range of altitude unaccessible to ground‐based or satellite measurements.
