Sondrestrom Lidar Operation Log

Operator(s) : E.Guðmundsson, Nathan Rausch
Purpose : Routine data collection. Test of the use of old damaged transmitter HWP removed from the system in 1998.
Date(s) : 030811 - 030811
File(s) : L20030811_001 - L20030811_005
Comments : Note, Chsopper settings chnaged during the experimt for sodium only.

Experiment run the Rayleigh transmitter hwp previously removed fromthe system
in 1998 due to damage.
