Estimation of the atmospheric CO2 concentration in Iraq

الملخص EN

The yearly average of the atmospheric CO2 concentration in (16) different stations over Iraq for thirty years ( 1961–1991 ) have been estimated by using sunshine duration, extraterrestrial radiation, global radiation, the clearness index, diffused solar radiation and gross CO2 assimilation of plants.

These parameters are used as an input data for some mathematical models.

The monthly rate of a gross CO2 assimilation of plants is calculated by using Light Use Efficiency Model (LUE) and solar radiation data of all locations for that period.

The monthly average of other parameters is calculated by using solar radiation model.

The results of the yearly average of the atmospheric CO2 concentration in Iraq is (362.4405 ppmv) that can be considered an acceptable one and closed to the global measured results (334.1171ppmv).
