Sondrestrom Lidar Operation Log


Operator(s) : A.Merkel
Purpose : Routine data taking, and first time Aimee Merkel ran the system by herself
Date(s) : 000527 - 000527
File(s) : L5270 - L5270
Comments : The skies look clear, there may be some intermitent clouds. I am having trouble
converging the Sodium channel. The oscilations are due to me trying to converge
the mirror.

As you can see from the data, there is only about 1-2 hours of good data. The
clouds came in and I thought that they were going to clear up. They didn't. I was
also having trouble converging theSodium channel with such a low signal. Other
than the clouds, the experiment when ok.
