Sondrestrom Lidar Operation Log

Operator(s) : Christian, Have, Pedersen, E.Guðmundsson
Purpose : Testing if we can reveive the 607 raman signal on the 589pmt
Date(s) : 070305 - 070305
File(s) : L20070305_000 - L20070305_001
Comments : Experiment was plaged by noise problmes, Identified noise source as the chopper
control signal of 2400Hz (10x240Hz).

Due high altitude cirrus clouds I feel that we did despite of that show that we were
indeed observing raman signal as the clouds that were very visible on the Rayleigh
channel did not show up on the raman profile.

		Running in a bit of a strange mode as we are trying to
		Take some data with Reyleigh and Raman shifted on the
		sodium channel. We have not changed the normal data
		acq setup in any way. The only change is a new filter
		stack in front of the normal 589 pmt allowing 607 to pass
		to and triggering of the sodium SR430 is now on 30Hz
		as the 532nm laser fires.
