Land surface temperature estimation using remote sensing technique: A case study Al-Ubaydh watershed, Al-Anbar Province, Iraq

Land Surface Temperature (LST) is an essential climate parameter, related to surface energy balance. The main objective of the present study use remote sensing and Geographical Information System (GIS) calculate land temperature Al-Ubaydh Basin, South Anbar governorate in Iraq. Split Window (SW) algorithms were applied on Landsat-8 infrared thermal band temperature. results showed that LST area ranges between 20.4 46.2 degrees Celsius October 2020, compared 25.7 63.7 June same year, both captured at 10:45 am. These indicate decreases eastern western regions as well towards center due agricultural sectors land/rock composition respectively. generated map generally compatible with previous studies base radiometers or a terrestrial camera provides direct measurements. Thus, this has demonstrated capabilities effective, low-cost, affordable tool can be used obtain LST.
