Fourier series and numerical techniques have been used to determine (hottest and coldest day) diurnal and annual temperature variation of the year 2015. The diurnal temperature variation is up to 0.2 m depth of soil whereas annual temperature variation is up to 3 m depth.}, keywords = {Soil temperature,Numerical,Fourier series}, url = {https://www.ije.ir/article_73044.html}, eprint = {https://www.ije.ir/article_73044_3009ee0c2688d73168d403d37ad7efea.pdf} }
