Sondrestrom Lidar Operation Log


Operator(s) : A.Merkel
Purpose : NLC detection and routine data taking
Date(s) : 000622 - 000623
File(s) : L6220 - L6220
Comments : The skies have intermittent clouds.

The rayleigh laser power started at 520 mJ. But we have seen by monitoring it
with the poser monitor that it drops to 480 mJ 10 minutes after startup. This
could be due to the new flashlamps or it may have been doing this all along but
there is no documentation.

No NLC detection
The sodium channel looked like it had a sporadic layer
