Summary

The Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR)
Data Base at NCAR/HAO holds data collected from the Qaanaaq Digisonde
at Qaanaaq, Greenland (77.5N, 69.4W) for 1989. The data consists of
velocity vectors derived from a least-squares fit of a Fourier
analysis of scattering from many irregularities in the F region of the
ionosphere. ... The digisonde has been in operation since 1983. The
Qaanaaq Digisonde is owned and operated by the U.S. Air Force Research
Laboratory (AFRL) at Hanscom AFB, MA.

Digisondes and ionosonde plots are described in:
http://ulcar.uml.edu.

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
(emery@hao.ucar.edu). See the WWW site for additonal information on
accessing the data and Rules of the Road procedures.
