Sondrestrom Lidar Operation Log


Operator(s) : A.Merkel
Purpose : NLC detection and routine data takinge
Date(s) : 000702 - 000703
File(s) : L7020 - L7020
Comments : The skies are cloudy. Intermittent cirrus.

The clouds went away and left a very clear night. Several NLC detections
occurred.
There were a couple of strong ones and several weak ones.

NLC detection!
