Sondrestrom Lidar Operation Log


Operator(s) : John, Geiszler, John Geiszler
Purpose : routine data collection
Date(s) : 050809 - 050809
File(s) : L20050809_000 - L20050809_011
Comments : Many data acquisition program errors. All of the restarts and approximate times
are noted in the logs. I'm pretty sure this must be a software error, as the
hardware was not malfunctioning/overheating/poorly connected. Unfortunately,
most of the crashes only affected one channel and did not have any associated
error, unlike the infrequent GPIB events.
Otherwise, data collection went well.
