Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson, Claus, Johannsen, Nathan Rausch
Purpose : Tweek and data collection
Date(s) : 040423 - 040423
File(s) : L20040423_001 - L20040423_003
Comments : Tweking resulted in improved counts although I don't like the shape of the
Rayleigh profile. It looks like it has some strange curvature to it just passed the
highest signal poing, I'm wondering weather this is due to counting parilising at the
high end?

Stopped tweeking arround 03:00 UT and closed the receiver for nromal data
collection.
