Ground-layer turbulence profiling using a lunar SHABAR
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 measure the variation of solar...
