Sondrestrom Lidar Operation Log

Operator(s) : Katelynn Greer
Purpose : Routine Data Collection, implement correct HWP offsets
Date(s) : 080802 - 080802
File(s) : L20080802_000 - L20080802_001
Comments : Adjusted HWP offsets and took routine data with the sun tracking w/ flipping
routine. There was a persistant cirrus cloud throughout. One minor NLC was
detected.
