Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson
Purpose : Test of PMT signal integrity
Date(s) : 031107 - 031107
File(s) : L20031107_001 - L20031107_001
Comments : Due to the shape of the Reyleigh profile in yesterdays run a test of count
uniformity as a function of altitude was deemed necessary.

The test was conducted with the lasers running and the beams beeing dumped into
the energy monitors. Telescope spider LED backlighting was used to provide
background light. Telescope cover was closed.
