Atmospheric gravity waves drive winds, temperature and chemical composition in the middle and upper atmosphere, but not enough is known about those that occur at higher altitudes. Now though, an ...

Surface Acoustic Wave (SAW) devices represent a class of sensors that exploit the propagation of acoustic waves through piezoelectric substrates to detect changes in mechanical and environmental ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...
