Sondrestrom Lidar Operation Log

Operator(s) : E.Guðmundsson
Purpose : Routine data collection
Date(s) : 020226 - 020227
File(s) : L20020226_000 - L20020227_001
Comments : Lidar room temperature was at the lowest I've seen this winter at startup or 19 deg
C. There was a small amount of drift in convergence and wavelength during the
~first two hours of the run. The room temperature had stabilized atsetpoint of
24deg C in the cource of these two hours.. No furhter tweeking was necessary for
the remainder of the run.

Conditions for the run were exelent, clear skies with no haze apparent.
