Abstract

This study has attempted to survey the relationship between temperature variations in Fars province and the variation in the rate of carbon dioxide emitted into the atmosphere. For this purpose, the temperature data (mean, minimum and maximum) of Shiraz, Abadeh, Lar, Doroodzan dam, Zarghan and Fasa stations, were extracted from Iran Meteorology Organization in a 15-year statistical period (1990-2005). First, the going trend in the temperature data of the above stations was studied. Then the relation between the rate of atmosphere carbon dioxide as registered in Manaloa station with the temperature parameters of these stations have been evaluated by using two-variable correlation and linear regression in both monthly and annual scale. The obtained results indicate that three parameters of mean, minimum and maximum temperature have the rising trend in all stations, among which the minimum temperature has allocated the highest rate of increase to itself. Furthermore, the results indicate that the highest correlation between the atmosphere carbon dioxide and temperature parameters is related to the months of February, March and October that the minimum temperature has allocated the highest correlation coefficient in both monthly and annual scale. Also, among the studied stations, the minimum temperature of Fasa station has the most significant coefficient with the rate of atmosphere carbon dioxide.
