The SOUSY - Svalbard - Radar (SSR)

Some examples of the SSR operation in 1999

Height-time-intensity plots of signal power P (lower panel) and radial velocity w in the vertical beam direction (upper panel), recorded with the SOUSY-Svalbard-Radar between 07:39:18 UT on 14 November 1999 and 01:35:05 UT on 15 November 1999, showing strong mountain lee waves.
The velocity scale is between -0.5 ms-1 (black) and +0.5 ms-1 (magenta); velocity estimates are affected by noise below and above the tropopause(~13 km). The power scale is between 0 dB at the noise level (yellow) and 40 dB (magenta).
