Sondrestrom Lidar Operation Log

Operator(s) : Christian Have Pedersen
Purpose : Data collection on Rayleigh and Sodium channel. Tuning of the sodium layer.
Date(s) : 070115 - 070116
File(s) : L20070115_000 - L20070116_001
Comments : Excellent conditions for LIDAR experiment. Tuning of the sodium layer verifies
the result from last exp. a week ago. The sodium layer peak in the profile is
maximized at a slightly higher wavelength.
Logfile : I1501070.log
