Sondrestrom Lidar Operation Log


Operator(s) : E.Gudmundsson
Purpose : Routine data collection
Date(s) : 990302 - 990303
File(s) : L9903020 - L9903033
Comments : A rather Bad run. Skyes were clear but noise from the HWP controller gave the
operator a hard time. Operator fiddled with the system which didn't improve
things. After things got better, a single noisy record (due to fiddeling) was
observed
and as this may F*** up processing, the operator tried to note the BOI. It's BOI
is aprox 3:41:31 plus minus a record or two. The run was cut short.

L990303000:06:24Had some noise problems13030
L990303000:12:26Rayleigh Convergence mirror adjusted13650
L990303100:56:19Still noise problems. incremented17370
L990303204:10:32Still working onthe noise, a single record on the rayleigh 0
channel had high background 20-30min ago. I didn't catch it
when it happend but noticed on the count history display
L990303204:43:41I think I got the noisy record down, its BOI is 3:41:31 +- a 0
record or two1853
