Abstract

A new Arctic stratospheric observatory (AStrO) has been established at Eureka (80 degree(s)N, 86 degree(s)W) in northern Canada. This observatory is one of the three designated components of the Arctic Primary Station of the Network for the Detection of Stratospheric Change (NDSC). Among the complement of sensors being installed at Eureka are two state-of-the-art lidar systems for monitoring stratospheric ozone and polar stratospheric clouds (PSC). The ozone Differential Absorption Lidar (DIAL) system utilizes a xenon chloride excimer laser transmitter operating at 308 nm as the absorbed `on' radiation. A hydrogen Raman shifter generates the `off' wavelength at 353 nm. The system provides an average output power of about 60 watts at 300 Hz. The receiver is a 1 meter Newtonian telescope provided with several special optical features to permit daylight operation. The second lidar utilizes a Nd:YAG laser source operating at 1064 and 532 nm with a 20 Hz prf. This paper describes the new lidar facilities at AStrO and presents a summary of the data obtained during the first months of operation.
