Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson
Purpose : Routine data collection and daystar alignment
Date(s) : 030327 - 030327
File(s) : L20030327_000 - L20030327_004
Comments : Prior to this run the TX hafwaveplate incident angle was reduced to the minimum
possible. The purpose beeing to see if there is a change in the amplitude of the
6hour signal modulation
