NOAA-SEARCH Atmospheric Observatory Program, Eureka, Canada
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).

The BROWSER allows viewing of:
- Input radar reflectivity and lidar backscatter.
Other fields that will become available:
- Microwave radiometer liquid water path and rawinsonde data
- Cloud classification masks
- Ice particle and/or droplet sizes
- Ice and/or liquid water contents
- Radar reflectivity, Doppler velocity and spectral width
- Radiometer brightness temperature, infrared at 10.6-11.3 microns and microwave at 23.8 and 31.4 GHz

*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.
Mindjet Doc of FTP area: The Eureka Mindjet Doc is an image/map that shows the organization of the Eureka FTP data site with accompanying links to the data folders.
