Within a short amount of years, urban land in Baghdad governorate increased as a result of the improvement of the economic factor of human beings, the speedy enlargement Buildings method brought many negative climate issues, for instance, the violent modification of land use and the growth UHI, which led to a decrease in vegetation cover, where influenced the temperature averages, Accordingly, we conducted the following study to find solutions, From 2008 to 2018, Landsat Information 5 and 8 were adopted in this analysis, show that urbanization is increasing rapidly as well as the impact of degrees Temperature in this change, was the source of temperature data (ECMWF) for the province of the study, and the results of the method (IDW) used for temperature mapping showed a change in the rates of temperature in urban areas, where the decline of vegetation impact on temperature rates, As well as commercial activities developed by people, which occupied some agricultural land, which led to negative results ,Several previous kinds of research show that the developed lands by humans will affect the local climate. The satellites used were Landsat 5 and 8, where the images of the study area were taken by these satellites during the study period and were entered into a program (ArcGIS) for the objective of modification and clear output. From the information obtained from the results, there is an inverse correlation between increasing urbanization and air temperature rates and positive correlation with solar radiation and wind speed. We conclude from this information that the development of green lands without good coordination will affect the local environment.

Air temperature (T air) near the land surface is a fundamental descriptor of physical environmental conditions and one of the most widely used climatic variables in global change studies. In this study, the researcher trying to suggest a model for estimating air temperature in summer season for any region through integrating of Iraqi Agrometeorological network
daily (T air) with the moderate resolution imaging spectroradiometer (MODIS) land surface temperature (LST), Duration Day Length (DDL) and Digital Elevation Model (DEM). In this model, using satellite images for the study area and data of air temperature for four weather stations located in Babylon governorate from 1- June to 30- September on year 2017 for modeling and accuracy assessment air temperature estimation. The standard error of this model is 1.72887° C, and the correlation equal to 0.69698.
