Sondrestrom Lidar Operation Log


Operator(s) : A.Merkel
Purpose : Data run and to look for NLC
Date(s) : 000609 - 000609
File(s) : L6090 - L6091
Comments : The skies have lots of high cirrus. A solar flare happened today so the probabilty
of seeing an NLC is minimum.

The dye in the sodium system was changed before this run.

The data set is ok. Thedata between the big clouds are good.

The clouds thickened around 5:45 so I am going to shutdown
