Empirical models for the correlations between total ozone column and latitude in different regions in Iraq

الملخص EN

This Research aimed at find a correlation between Total Ozone Column (TOC) and Latitude in different regions in Iraq using several Mathematical Models.

Models were used for that [Linear Models, Quadratic Models, Exponential Models, Logarithmic Models, Power Models].

Several statistical tests [R2 , R, MAE, RMSE] were used to control the validation and goodness of these Models.

Quadratic Model gavethe highest R 2 among the other models in all stations.

R 2 obtained between (TOC) & Latitude in Winter & Spring months were very high and ranged between (0.953 – 0.

976).Summer months show a good correlation in June & July and week correlation in August.

In Autumn months a good correlation was obtained in October & November and week correlation was obtained in September.The highest R2 means that there is a highly significance correlations between Total Ozone Column and Latitude.This mean that these Models gave a very good results to estimate(TOC) from Latitude.
