Sondrestrom Lidar Operation Log


Operator(s) : Christian, Have, Pedersen, E.Guðmundsson
Purpose : final tweeking of rayleigh after receiver modifications this summer. Traing of the new lidar jock.
Date(s) : 060920 - 060920
File(s) : L20060920_000 - L20060920_000
Comments : looks like the performance of rayleigh system is good. things that need to be
addressed are waveplate rotation direction (TX and RX) and possible signal induced
noise performance. Iris settings need to be looked at.
