Ionospheric Doppler Radars from the CEDAR Data Base at NCAR/HAO

The Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) Data Base at NCAR/HAO holds data collected from HF ionospheric doppler radars. The HF radars are organized into a community called SuperDARN. Eleven of these radars have data in the CEDAR Data Base. The basic parameters are the line-of-sight plasma irregularity velocity and velocity spread. Most of the HF radar data can be obtained from the contacts for each of the HF radars:

1. HF data from the SuperDARN station at Halley, Antarctica (75.5S, 26.6W). The CEDAR Data Base contains data from 6 campaigns between 1990 and 1995. The station has been in operation since 1988. The contact person is Michael Pinnock. The Halley HF radar is jointly supported by the British Antarctic Survey and the NSF Division of Polar Programs.

2. HF data from the SuperDARN station at Syowa, Antarctica (69.02S, 39.56E). The CEDAR Data Base contains data from one campaign in 1995. The station has been in operation since 1995. The contact person is Natsuo Sato. The Syowa HF radar station is operated by the National Institute of Polar Research in Japan.

3. HF data from the SuperDARN station at Kapuskasing, Canada (49.39N, 82.32W). Data from 15 campaigns since 1993 are in the CEDAR Data Base. The station has been in operation since 1993. The contact person is Michael Ruohoniemi. The station at Kapuskasing is operated by the Applied Physics Laboratory of The Johns Hopkins University with support from NASA and the NSF.

4. HF data from the SuperDARN station at Saskatoon, Canada (52.16N, 106.53W). Data from 15 campaigns since 1993 are in the CEDAR Data Base. The station has been in operation since 1993. The contact person is George Sofko. The Saskatoon HF radar is operated by the University of Saskathewan with support from the Natural Sciences and Engineering Research Council of Canada.

5. HF data from the SuperDARN station at Goose Bay, Canada (53.32N, 60.46W). Data for 25 campaigns since 1988 are in the CEDAR Data Base. The contact person is Michael Ruohoniemi. The Goose Bay HF radar is operated by the Applied Physics Laboratory of The Johns Hopkins University with support from the NSF.

6. HF data from the SuperDARN station at Hankasalmi, Finland (62.32N, 26.61E). Data for 7 campaigns since 1995 are in the CEDAR Data Base. The station has been in operation since 1995. The contact person is Mark Lester. The radar is operated by the Radio and Space Plasma Physics Group at the University of Leicester with support from the Particle Physics and Astronomy Council and the Finnish Meteorological Institute and the Swedish Meteorological Institute.

7. HF data from the SuperDARN station at Stokkseyri, Iceland (63.86N, 22.02W). Data for 11 campaigns since 1995 are in the CEDAR Data Base. The station has been in operation since 1994. The contact person is Jean-Paul Villain. The Stokkseyri HF radar is operated by CNRS/LPCE and CNRS/CETP with support from the Institut National des Sciences de l'Univers.

8. HF data from the SuperDARN station at Pykkvibaer, Iceland (63.86N, 19.20E). Data for 6 campaigns since 1996 are in the CEDAR Data Base. The station has been in operation since 1996. The contact person is Mark Lester. The HF radar station is operated by the Radio and Space Plasma Physics Group at the University of Leicester with support from the Particle Physics and Astronomy Council and support from the Finnish Meteorological Institute and the Swedish Meteorological Institute. 9. HF data from the SuperDARN station at Kerguelen Island (49.35S, 70.28E; 58.9 magS), operated by CNRS, France since July 2000. The radar is southward scanning and Syowa-East HF radar data are the most direct for 2-D merging of the Kerguelen velocity data. Data for one campaign in 2000 are currently in the CEDAR Database.

10. HF data from the SuperDARN station at the South African National Antarctic Expedition (SANAE) site in Antarctica (71.68S, 2.85W; 62.0 magS). SANAE is run by the University of Natal and the Potchefstroom University for Christelike Hoer Onderwys (PUCHE) and has been in operation since 1997. SANAE is westward scanning and Halley is the other HF radar for the most direct 2-D merging of SANAE velocity data. The Database contains data from 1 campaign in May 1999.

11. HF data from the SuperDARN station at Syowa-East, Antarctica (69.02S, 39.56E; 64.9 magS), operated by the National Institute of Polar Research in Japan since 1997. The radar is eastward scanning and Kerguelen HF radar data are the most direct for 2-D merging of the Syowa-East velocity data. Data for one campaign in 1999 are currently in the CEDAR Database.

The CEDAR Data Base is accessible through the WWW and ftp, but users must have a valid access form, available from the WWW or ftp (see Access and Use constraints) or contact Barbara Emery ([e-mail]). See the WWW site for additional information on accessing the data and Rules of the Road procedures.
