Coupling, Energetics, and Dynamics of Atmospheric Regions

Project Description
Coupling, Energetics and Dynamics of Atmospheric Regions (CEDAR) is a
focused Global Change program sponsored by the National Science
Foundation (NSF) 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 (formerly 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. There are 10 GB of data on
the computer in the High Altitude Observatory (HAO)
division of NCAR.
The CEDAR Data Base, Data Base Catalog, ftp site, and model output data
are located at the HAO:
The CEDAR concept originated in the mid-1980's and was developed over
several years through workshops, symposia, and committee deliberations
by nearly 100 scientists involved in aeronomical studies. These
activities led to a comprehensive report that provided a framework for
developing upper atmospheric research in the United States through an
evolutionary strategy of instrument development and deployment
coordinated with campaign activities related to the globalscale,
coupled, nearearth environment. The program has attracted a large
number of graduate students and many international
collaborators. Guidance is provided by a science steering committee
appointed by the NSF Aeronomy and Upper Atmospheric Facilities program
directors; scientific feedback to the community is provided by
newsletters and an annual summer workshop.
Three broad categories embrace the scientific goals of the CEDAR
program: (1) dynamics and energetics of the upper atmosphere, with
particular emphasis on the hard to observe region between 80 and 150
km; (2) coupling between the mesosphere, ionosphere, thermosphere,
exosphere, and magnetosphere; and (3) horizontal coupling between
adjacent geographic regions. CEDAR has provided the community with
improved spectrometers, interferometers, and imagers; allowed upgrades
of existing facilities; and supported the development of lidars and
small radars. Several facilities have been established containing a
broad array of state of the art tools to provide a solid
infrastructure with which to attack outstanding aeronomy problems well
into the future.
