Lidar Measurements in 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 Lidar
measurements. Basic parameters measured include photocounts, relative
neutral number density, and sodium or iron density depending on
wavelength used. Neutral temperatures and winds can be derived from
the Lidar data, however, winds are not in the CEDAR Data Base. The
Lidar data in the CEDAR Data Base are:

1. Rayleigh/sodium and iron lidar data from the University of Illinois
lidar. The sodium lidar operated in January-April 1989 at Arecibo,
Puerto Rico (18.35N, 66.75W) and in an aircraft over
Hawaii (20N, 155W) in 1990. The iron lidar was operating at Urbana
(40.1N, 88.1W) during October 1989 and March 1991 to August 1992. See
the University of Illinois Lidar Listing for dates of lidar data in
the CEDAR Data Base: The contact person is Chester Gardner. The University of Illinois
CEDAR lidar is operated by the University of Illinois with support
from the NSF.

2. The sodium lidar data was taken with the Colorado State University
lidar at Fort Collins, CO (40.59N, 105.14W). Data for 1993 are in the
CEDAR Data Base. The lidar began operations in 1990. The contact
person is Chiao-Yao She. The Colorado State University sodium lidar is
operated by the Colorado State University with support from the NSF.

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 additonal information on
accessing the data and Rules of the Road procedures.
