20071208_00522:12:46Start of experiment00cp
20071218_00522:15:34First 6 data files of Raman data are rubbish.0cp
First 4 data files of Rayleigh data are rubbish
22:17:58Conditions not so good. Thick haze layer.0cp
22:18:18Will be working on the IR channel .0cp
22:34:53The LIDAR PC has been formated, because it really needed0cp
it !!. Some small problems initializing the ARCLITE apps.
The automatic datafile and noise count update is not yet
functioning, but otherwise everything works.
22:56:57Profiles looks better now. 2370cp
23:35:29Cabinet open now.5910cp
23:51:12Taking down laser for 2 min.0cp
00:00:36Up again. Cabinet closed again.0cp
00:02:25Haze is back.1740cp
00:13:09Looked like the 532 PMT was saturated by the Haze returns0cp
so I moved up the chopper a notch. The chopper heigth
was probably too low.
00:53:36Conditions bad right now.0cp
01:15:08Blast, massive cloud cover now. Will have to end.0cp
01:15:26End of experiment0cp
