COSPAR International Reference Atmosphere from NSSDC
Listed in NASA Earthdata CMR
The COSPAR International Reference Atmosphere (CIRA) provides empirical models of atmospheric temperature and densities as recommended by the Committee on Space Research (COSPAR).
Description
Since the early sixties different editions of CIRA have been published. The CIRA Working Group meets bi- annually during the COSPAR general assemblies.
CIRA-86 is described in Advances in Space Research, Volume 8, Numbers 5-6, 1988; a more extensive report will be published as MAP Handbook. In the thermosphere (above about 100 km) CIRA-86 is identical with the MSIS model which is described in a separate MD entry. The lower part (0-120 km) consists of tables of the monthly mean values of temperature and zonal wind with almost global coverage (80N - 80S).

Two files exist, one in pressure coordinates including also the geopotential heights, and one in height coordinates including also the pressure values. These tables were generated from several global data compilations including ground-based and satellite (Nimbus 5,6,7) measurements: Oort (1983), Labitzke et al. (1985). The lower part was merged with MSIS-86 at 120 km altitude.
In general, hydrostatic and thermal wind balance are maintained at all levels. The model accurately reproduces most of the characteristic features of the atmosphere such as the equatorial wind and the general structure of the tropopause, stratopause, and mesopause. The CIRA-86 tables are available from NSSDC on diskette (5 1/4 or 3 1/2 inch) and online over NSI/DECNET.
