Ground-layer turbulence profiling using a lunar SHABAR
International audience Profiling the ground layer turbulence for daytime seeing applications using an array of photodiodes has been documented in literature, in particular by Beckers who coined the term "SHABAR" for the instrument, short for Shadow Band Ranger. In this case the photodiodes...

International audience Profiling the ground layer turbulence for daytime seeing applications using an array of photodiodes has been documented in literature, in particular by Beckers who coined the term "SHABAR" for the instrument, short for Shadow Band Ranger.
