Empirical Models for the Correlations Between Total Ozone Column and Latitude in different regions in IRAQ

Abstract

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 gave the highest R² among the other models in all stations. R² 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.
