Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson, John, Geiszler, John Geiszler
Purpose : data collection
Date(s) : 050725 - 050726
File(s) : L20050725_000 - L20050726_004
Comments : a long and eventful run, but not in terms of NLCs. Maintenance work on both Na
and Rayleigh lasers might be necessary in the near future.
