Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson
Purpose : Routine data collection coinsistent with IS radar operations
Date(s) : 030301 - 030301
File(s) : L20030301_000 - L20030301_001
Comments : Little attention to the run in the first half due to focus on Radar problems.

Run was hampered due to cirrus clouds and was ended due to low counts.
