Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson, J.Jørgensen, T.Jørgensen
Purpose : Routine data collection, sensitivity caracterization as a function of solar zenith angle.
Date(s) : 010614 - 010615
File(s) : L106140 - L106152
Comments : Prior to this run a fixed 0.6mm diameter iris was installed in the system in an
atempt to press down the FOV overfill ratio between telescope and laser beam.
