Sondrestrom Lidar Operation Log

Operator(s) : E.Guðmundsson, J.Jørgensen, C.Heinselman
Purpose : Routine data collection. Coordinated with IS Radar, Craigs run.
Date(s) : 010210 - 010212
File(s) : L102100 - L102116
Comments : Dye laser HWP position during the run 150deg (Maximum Rayleigh attenuation)

Receiver HWP position during the non tracing section of the run was 183 deg as
read from scale on HWP mount. Note this is the "resting" position of the Rx
HWP when not in use.
