Sondrestrom Lidar Operation Log


Operator(s) : E.Gudmundsson
Purpose : Routine data collection Rayleigh only
Date(s) : 990415 - 990416
File(s) : L9904150 - L9904152
Comments : Baaad first half of run, had problems with the Rayleigh convergence trougout
the
first half. Nice and clear skies though! Managed to get counts upto around 1800
max during the latter half of the run. Looked back on Daystar data and it looks
like, from the last run that the transmission of the daystar is around 20%, it
should
be around 30%!
