[ 1 ] - استخراج روابط رگرسیونی بین دمای خاک در اعماق مختلف و پارامترهای هواشناسی (مطالعه موردی: ایستگاه همدان)

In this research, we estimated soil shallow depths temperatures using regression methods (Linear and Polynomial). The soil temperatures at soil depths (5, 10, 20, 30, 50 and 100 cm) were correlated with meteorological parameters. For this purpose, temperature data of Hamedan station (in the period 1992-2005) were employed. Soil temperature data were measured on a daily basis at 3 PM, 9 PM and 3...
