Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson
Purpose : Routine data collection NLC campaign
Date(s) : 030624 - 030626
File(s) : L20030624_000 - L20030626_007
Comments : Due to the absence of the news data display (due to a fault on Umimmak), this
run
was run without any displays.

For the same reason no logs were made real time. This log was created by
reviewing the data after the run.

Several NLC's were detected during the run.
