Sondrestrom Lidar Operation Log


Operator(s) : Claus, Johannsen, E.Guðmundsson, T.Jørgensen
Purpose : Traning and Data aq.
Date(s) : 030528 - 030528
File(s) : L20030528_000 - L20030528_007
Comments : singal normal in the night configuration. Chopper needs position optimizing and
the field stops need to be configured better. daystar installed without atempts to
optimize du to radar work bur signal was good but still further work is needed on
the
daystar.
