Projections of future soil temperature in the western part of the Southeastern Anatolia Project region, Türkiye

This dataset contains forecasted and corrected daily air and soil temperature data for the years 2030, 2050, 2070, and 2090 at the Siverek and Birecik stations in the Southeastern Anatolia Project (W-SAP) region of Türkiye. The data is based on climate projections under the RCP4.5 and RCP8.5 scenarios, generated using 17 Global Circulation Models (GCMs) along with the MarkSimGCM tool. The Soil Temperature and Moisture Model (STM2) was utilized for this analysis (Jones and Thornton 2013).

Daily air temperature data, including maximum and minimum temperatures, as well as soil temperature data at various depths (5, 10, 20, 50, and 100 cm), were obtained from the MarkSim weather generator. Additionally, precipitation and solar radiation data were provided by the same generator. These datasets were employed to calibrate the STM2 model and to evaluate future soil temperature trends. Historical data from 2003 to 2006 were used for bias correction. Information regarding organic matter and soil texture necessary for the model was sourced from the Harmonized World Soil Database (HWSD) version 1.21 Imager (FAO/IIASA/ISRIC/ISS-CAS/JRC, 2012)
