Interim Reference Ozone Models for the Middle Atmosphere

Abstract

A set of models was generated based on six satellite experiments of the monthly latitudinal variations in total column ozone and the vertical structure of ozone from 20 mb to 0.003 mb. Generally, interannual variability in monthly zonal means is only a few percent. Comparisons of measurements using various techniques to measure global ozone reveal very good agreement between the techniques. Agreement between individual satellite experiments and the reference model of monthly zonal means is generally within 10% below altitudes of 0.4 mb. This has allowed the first global model of ozone measurements to be constructed from multiple sets of satellite measurements. The ozone measurements based on the satellite data are in excellent agreement with previous midlatitude mean annual model based on rocket and balloon data. Also, models are provided of the relation between total ozone and vertical structure.
