Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson, J.Jørgensen, T.Jørgensen
Purpose : Run coordinated with the IS radar, Craig Heinselman SRI.
Date(s) : 020527 - 020529
File(s) : L20020527_000 - L20020529_000
Comments : While taking data on the Sodium Noise problems on the Rayleigh were addressed.
A large 60Hz component is contaminating the Rayleig data. No solution found
during the run. Did som alignment on the Daystar as well.

20:37:50Cloudy out there. No signal so far...0JJ
20:51:41Time was off about -2 min and 57 secs. Before this point0JJ
20020527_00100:32:50Eggert fixed the sodium channel so we are seeing something0JJ
00:36:10Turned record off for the rayleigh channel because the signal0JJ
is contaminated with 60 cycles
