Sondrestrom Lidar Operation Log


Operator(s) : E.Gudmundsson
Purpose : Routine data collection
Date(s) : 981023 - 981023
File(s) : L9810230 - L9810232
Comments : There were some stability problems with the Reyleigh system convergence in the
beginning of the run but this stabilized later on. A clear night long awaited.
