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

*Datagram: A “Datagram” is intended to serve as a virtual data mentor to anyone who comes in contact with the data file or the instrumentation that is used to generate fields within that file. While a data user will ideally collaborate closely with a principal investigator, “Datagrams” provide a structured basis for independent inquiry and logical information exchange about data processing.

Data is also available through FTP. See the Data Page.
