This research aims at studying and understanding the full capabilities of West Azerbaijan province for sunflower cultivation. Geographic information system (GIS) was used to carry out the research. Climate data elements such as the minimum temperature during the growing season (May to September), the rainfall during the growing period, the relative humidity during growth of sunflower, were prepared in 9 stations in the region between the years (1387-1373). Slope, soil and elevation data were included to determine and identify the appropriate area of study in the range of sunflower cultivation.
Using vegetative needs (favorable climatic conditions) of the crop, the production of information and data rate of each series were classified. In order to investigate the influence of each element in the earth's climate and physical factors affecting agro-climatic planting of sunflower, the data on temperature, precipitation and relative humidity were combined and then all data elements in the earth's climate and physical factors together were then integrated. The final map of the land capability for planting of sunflower was produced. Finally, the AHP model, and overlapped data in both weighted area of Zone 2, were used. Sunflower planting area in the north east and eastern parts of the study area (the city of Khoy, Qara Zyaaldyn, Poldasht and Shoot) was specified. The areas suitable for cultivation in both models were chosen to be the city of Qara Zyaaldyn and Poldasht.

In a wide variety of scientific climatology studies earth surface temperature, is important, Astronomy, meteorology hydrology, ecology, geology, medical science, design and optimization of transportation network and site selection of fire extinction and particularly cases required. In the calculation of the actual evapotranspiration also we consider these.. Considering the earth's surface temperature monitoring in a limited number of meteorological stations to the distribution point and the need to place the surface temperature in a wide area and at the same time the surface temperature were estimated. To access the earth's surface temperature and classification SEBAL algorithm and decision tree were used. Using ETM + image dated 31 August 2000 and pre- process, files became ready for implementation. For processing of SEBAL method. the above mentioned software Envi4.5 and ArcGIS9.3 were used. This paper estimates the difference less than 5.57° C, temperature difference between a satisfactory level was estimated through remote sensing and statistics. Temperature measured from ground level 12 years (1993 - 2005) in Maragheh meteorological station was achieved. Temperature was estimated through remote sensing and studies applicable in earth sciences research and the environment.
