Sondrestrom Lidar Operation Log

Operator(s) : E.Guðmundsson
Purpose : Routine data collection
Date(s) : 020127 - 020128
File(s) : L20020127_000 - L20020128_002
Comments :
Started the run with Rayleigh only.
Sodium system started 22:46 UT.

Temperature out of control in Harris and Lidar room as a result of operator
mistake Last Firday (was ventilating van 1 and forgot to put things back). As a
result the usual unstability in the system was observed as the temperature rose to
the propper setpoint!
