A radar echo-contour height measurement at different gain
settings of the receiver, from RHI pictures shows that heavy rain
occurs at the points above which steep echo-contour gradients appear.
In this study, radar data came from the AN/CPS-9 radar
located at McCulloch peak, about five miles from the Oregon State...
Fourier transformed amplitudes of the compressional waves
recorded between 9° and 91° (about 1000 to 10,000 km) epicentral
distance from Gnome, Shoal, Haymaker,and Bilby underground
nuclear explosions have been compared with Fourier transformed
amplitudes of P waves measured at distances between 9.0 and
1 3. 0 km from the explosions....
