A successful collaboration between the U.S. NOAA-SEARCH Atmosphere Program, the Canadian CANDAC Program, Meteorological Services Canada and the University of Wisconsin Lidar Group resulted in the installation of a cloud radar and cloud-aerosol lidar in Eureka, Canada in August of 2004. These instruments are the first of a comprehesive suite of radar, lidars, radiometers, wind profilers, inteferometers, chemistry and aerosol sensors that will be part of a long term Atmospheric Observatory at the Eureka site.

Daily updates are made at this site of observations from the radar (pdf description) and the lidar (Lidar description at U of W). More comprehensive data products for the lidar can be found at http://lidar.ssec.wisc.edu/syst/ahsrl/ahsrl_data.htm.
