Troposphere height has extensive interaction with other atmospheric components; it gives a good indication of what happened inside; therefore, this work tried to investigate the heat rate effect on troposphere height, especially after the global warming intensity and increased temperature degree rate along the time; thus the study covered 13 years to understand the real behavior of troposphere. Data for this work was given from the European center for medium-range weather forecasting (ECMWF) over Baghdad city, the result showed that there is a fluctuation in troposphere height, and the difference between a higher and lower point in winter was about (120 m), and that was higher than its rate on summer which was about only (30 m), also the result denoted that the fluctuation frequency becomes lower in the late of the study period. On the other side, the study found that the coherence between temperature and troposphere height fluctuation becomes higher in summer than in winter. Still, in general, the troposphere height recorded an increasing trend over time of the study period. Keywords: Troposphere height, Temperature, Baghdad city, ECMWF, Seasonal variation.
