Syntax
Description
[
implements the mathematical representation of the Committee on Space Research (COSPAR)
International Reference Atmosphere (CIRA) 1986 model. The CIRA 1986 model provides a mean
climatology using a latitude T

and representation of coordinate
type ctype
. The mean climatology consists of temperature
T
, zonal wind zonalWind
, and pressure or
geopotential height pressureOrAltitude
. It encompasses nearly
pole-to-pole coverage (80 degrees S to 80 degrees N) for 0 km to 120 km. This provision also
encompasses the troposphere, middle atmosphere, and lower thermosphere. Use this
mathematical representation as a function of pressure or geopotential height.
This function uses a corrected version of the CIRA data files provided by J. Barnett in July 1990 in ASCII format.

Limitations
This function has the limitations of the CIRA 1986 model and limits the values for the CIRA 1986 model.
The CIRA 1986 model limits values to the regions of 80 degrees S to 80 degrees N on Earth. It also limits geopotential heights from 0 km to 120 km. In each monthly mean data set, the model omits values at 80 degrees S for 101,300 pascal or 0 m. It omits these values because these levels are within the Antarctic land mass. For zonal mean pressure in constant altitude coordinates, pressure data is not available below 20 km. Therefore, this value is the bottom level of the CIRA climatology.
