Infrasound station PVCI (50.53°N 14.57°E) from the Czech microbarograph network, C9 (https://doi.org/10.7914/SN/C9) is integrated in the Central and Eastern European Infrasound Network (CEEIN, www.ceein.eu). A correct evaluation of detections on the station level is essential for network data processing and localization and identification of events. To improve the knowledge of the infrasound...
A thunderstorm is a well-known and permanent source of infrasound events. Infrasound signal propagation is known as well to be dictated by atmospheric parameters like temperature and wind. In a tropical region like Madagascar, rainfall pattern is one possible technique used to explain seasonal variation of International Monitoring System infrasound network detectability. In this study, 20...
The atmosphere is changing on a wide variety of timescales. The infrasound component of the International Monitoring System (IMS ) can sense such changes, each second over periods of tens of years. Such long term measurements of atmospheric variability enable the study of climate change. Infrasonic waves passively probe the entire atmosphere. The challenge is to unravel temperature variability...
Understanding the impacts of near-field air flow on the long range transport of radionuclides in the atmosphere after a release from an underground nuclear explosion requires improved modeling at the local scale. In this work, we present the design of a radiotracer experiment in a complex terrain environment in support of modeling improvements. A remotely controlled release of Xe-127 gas,...
A massive explosion in Tianjin occurred at a container port on August 12, 2015. The explosion produced a strong infrasound of extremely high signal to noise ratio registered by domestic infrasonic stations several kilometers away. Different from the ordinary explosion infrasound, Tianjin explosion infrasonic signals appear as six consecutive groups of clear first arrival. This reveals the...
