Sondrestrom Lidar Operation Log

Operator(s) : Katelynn, Greer, Katelynn Greer
Purpose : Routine Data Collection and an experiment manually flipping HWPs to examine 607 channel modulation
Date(s) : 080812 - 080812
File(s) : L20080812_000 - L20080812_003
Comments : Routine Data Collection. One hour was spent with the HWP controller powered
off and the TX HWP was manually flipped.
