Sondrestrom Lidar Operation Log


Operator(s) : A.Merkel
Purpose : Routine data collection and looking for NLCs
Date(s) : 000610 - 000611
File(s) : L6100 - L6101
Comments : The experiment started at sza 75.8 while the sun is setting. The forecast is for
extremely clear skies. There are a few high cirrus right now. the Rayleigh signal
looks good. Have good snr up to 60 km.

This is a good data set. Not many clouds and good sodium and rayleigh signals the
whole time
