METOZ - TOTAL OZONE FROM METEOROLOGICAL PARAMETERS

On the basis of two well-known ozone-weather relationships an algorithm is proposed that estimates total ozone amounts using readily available meteorological information. The technique has been labelled METOZ from Meteorological Total Ozone. A rationale and derivation of the technique is presented METOZ total ozone amounts were generated for Toronto and Edmonton locations and compared with ground-based Brewer spectrophotometer measures for these two stations in the Canadian ozone monitoring network for data from January to April 1989. Per cent differences between METOZ and Brewer total ozone measurements were calculated and are presented. This mid-latitude winter METOZ algorithm was also used to produce a hemispherical total ozone field for 16 March 1986, which was compared with the corresponding Toms data to demonstrate other potential
