Turbulent pressure fluctuations around infrasound sensors, known as wind noise, are the primary factor masking infrasound detections of interest, such as signals generated by natural hazards. Identifying deployment sites with sufficiently low wind noise levels is crucial for achieving good signal to noise ratios. Noise levels are expected to correlate with local topography, which influences...
As infrasound sensors have become more compact and highly accurate, the true picture of various phenomena is becoming clearer through precise and dense observation.
Considering such kind of background, we attempted to observe the infrasound signals generated by explosion events to understand the actual state of waveform deformation and attenuation due to propagation. We know that the...
Atmospheric transport models (ATMs) are used for many important applications, including fate and transport simulations of radionuclides emitted to the atmosphere (forward modeling) and determining the possible origin of release of radionuclides measured by the International Monitoring System (backward modeling). Large meteorological data sets are needed by ATMs, which are generated and updated...
