Summary

Abstract: The Coupling, Energetics, and Dynamics of Atmospheric regions (CEDAR) is a
program sponsored by the National Science Foundation (NSF) designed to enhance
the capability of ground-based instruments to measure the upper atmosphere and
to coordinate instrument and model data for the benefit of the scientific
community. The CEDAR Data Base (formally the Incoherent Scatter Radar Data
Base) is a cooperative project between the National Center for Atmospheric
Research (NCAR) and several institutions that provide upper atmosphere data and
model output for community use. The CEDAR Data Base contains: documentation,
catalogue information, geophysical indices, summary plots, analysis software,
and computer models. A catalogue is produced every year and is available on the
WWW at:
http://cedarweb.hao.ucar.edu/wiki/index.php/Main_Page

CEDAR instruments are located throughout the world. Only selected data from
each instrument is available in the CEDAR Data Base. The on-line CEDAR Data
Base contains information to contact investigators for additional data not
found in the Data Base.

The CEDAR Data Base currently contains approximately 10GB of data. A
complete inventory of data and data availability is obtainable from
the following:

http://cedarweb.hao.ucar.edu/wiki/index.php/Main_Page

The CEDAR Data Base consists of the following:

Geophysical Indices. Includes Dst, Kp, ap, Ap, solar 10.7 cm flux,
sunspot number, AE, and IMF parameters.

Large Model Output. Includes model output from the Assimilative
Mapping of Ionospheric Electrodynamics (AMIE), Thermosphere Ionosphere
General Circulation Model (TIGCM), and Global-Scale Wave Model (GSWM).

Incoherent Scatter Radar. This is the primary data in the CEDAR Data
Base. Includes ionospheric electron densities, ion velocities, and
electron and ion temperatures.

Ionospheric Doppler Radars. HF ionospheric doppler radars are organized into a
collection of radars called SuperDARN (Super Dual Auroral Radar Network).
Eleven radars have data in the CEDAR Data Base. Basic parameters include
line-of-sight plasma irregularity and velocity spread.

Digisondes. Consists of ion drift data from the Qaanaaq Digisonde.

Fabry-Perot Interferometers. Basic parameters from FPI are
brightness, neutral temperature, and line-of-sight neutral winds.

IR Michelson Interferometers. Data include neutral temperatures
derived from nightglow hydroxyl (OH).

Lidar. Basic Lidar parameters are photocounts, relative neutral number
density, and sodium or iron density.

Middle Atmosphere Radars. Data are from MST radars, MF radars, LF
radars, meteor wind radars and ST radars. There is only limited data
in the CEDAR Data Base. Parameters include line-of-sight neutral winds
and turbulence.

Airglow Imagers and All-Sky Cameras. Data includes brightness data
from imagers. None of the imager data are in digital form. Some
airglow data is on video tape.

Models. Consists of both theoretical models and empirical models.
Source code is available from the CEDAR Data Base. Model output
consists of geomagnetic field data, electron densities, electric
fields, interpolations and models of NOAA and DMSP satellite data,
wind models, ionospheric parameters, and other data.

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@ucar.edu ). See the WWW site
for additional information on accessing the data and Rules of the Road
procedures.
