Sondrestrom Lidar Operation Log


Operator(s) : E.Gudmundsson
Purpose : Brent Watkins. Run coordinated with IS Radar
Date(s) : 980418 - 980419
File(s) : L9804183 - L9804186
Comments : Had major problems tuning the sodium system. High background and low power
caused the difficulties. Managed to get resonable resuts but very late in the run.
