| Climate changes and agricultural development processes have a dynamic interaction effects, however, climate change effect on the agricultural biophysical resources and productivity. On the other hand, the agricultural adaption scales and practices effect on the micro/macro climate parameters. Therefore, monitoring and change detection of climate change parameters may be an effective for enhancing the agriculture processes efficiencies. Hereby, the aim of this study was to determine the potential evapotranspiration as reflected with the thermal surface temperature (LST) under climate change conditions of Egypt.Regarding, LST and T average data indicate a decreasing values within about (-1˚c and -1.25˚c) had been observed respectively during the study period (1985 – 2017). A predicted equation for estimating the relationship between LST based on NDVI and microclimate parameters had been observed under climate change conditions of Egypt may be statically as follows: LST = 21.185 - (11.323*NDVI) + (0.459Tmean) + (0.7*SR) – (0.078*RH) – (0.587*WS) + ((0.364*TDEW) A statistically – significant linear trend between annual LST and T average with R² is ≈ 0.76 and LST with reference Evapotranspiration ETo with R² is ≈ 0.59, had been obtained. | ||
