Sondrestrom Lidar Operation Log

Operator(s) : J.Geddes
Purpose : Routine data collection
Date(s) : 980722 - 980722
File(s) : L9807220 - L9807222
Comments : The logsheet has been reconstructed due to a mishap with the logsheet program.
The starting and ending times are correct, as is the time of the switch from
532nm
filter to Daystar. A cloud passed through during the run. Attempts to adjust the
Daystar filter resulted in no observed changes in counts.
