Sondrestrom Lidar Operation Log


Operator(s) : John, Geiszler, John, Geiszler, John Geiszler
Purpose : Data Collection
Date(s) : 050625 - 050626
File(s) : L20050625_000 - L20050626_004
Comments : Na laser interrupted by fault in timing box ~12:10AM GMT. Reset and running
again by ~12:23AM GMT.
Had significant difficulty keeping the Rayleigh data collection running. Some
ARCLITE2 crashes. Strangely they affected only the Rayleigh channel, so I
initially missed them. Now I know what to look for and hopefully can avoid this
in the future. I had to stop and restart the data collection once ~1:16AM GMT.
~7:17AM GMT Another brief interruption in the timing box. Caught this one
right away and fixed it within about 2 minutes.
