Sondrestrom Lidar Operation Log


Operator(s) : John Geiszler
Purpose : Routine Data Collection
Date(s) : 050702 - 050703
File(s) : L20050702_000 - L20050703_000
Comments : Dye laser power is a little low. The dye should probably be changed soon.
Attempted an adjustment to the Rayleigh receiver alignment, but might have
made things worse. Eggert came by and helped me correct the receiver alignment.
Haze layer appeared this evening unexpectedly, so I shut down just after
2:15GMT.
