Sondrestrom Lidar Operation Log


Operator(s) : E.Guðmundsson, T.Jørgensen
Purpose : Routine data collection and system verification - co radar
Date(s) : 010329 - 010330
File(s) : L103290 - L103301
Comments : First run after the recevier has bee out of service during the etalon tests. Rayleigh
SR430 receives its trigger by way of a photodiode in the 532nm output path.
