Sondrestrom Lidar Operation Log

Operator(s) : E.Gudmundsson
Purpose : Routine Data collection
Date(s) : 981017 - 981018
File(s) : L9810170 - L9810171
Comments : This is the first data set taken on the new lidar gateway computer. As the setup is
not complete, there are no counts and filenumbers for each comment line on the
logsheet. This will be corrected before the next run. EG.
