Data associated with manuscript ("An Effective Medium Theory-Based Unified Model for Estimating Thermal Conductivity in Unfrozen and Frozen Soils") submitted to Water Resources Research

Datasets associated with manuscript “An Effective Medium Theory-Based Unified Model for Estimating Thermal Conductivity in Unfrozen and Frozen Soils” submitted to WRR<br>The dataset includes two excel files. One is "optimized models for selected samples.xlsx", and the other is “trained unified &amp; testing 3 models.xlsx”."optimized models for selected samples.xlsx": three soil samples with measurements were selected to present the ability of the unified model and existing models. These models were optimized to best fit the measurements.Columns:“measurement”: measured thermal conductivity;“ck2005”, “tian2016”, “gd2016”, “unified”: predicted thermal conductivities by the individual models;“fr_high”: high-conductivity fraction. It is liquid water content for unfrozen soils, and liquid and ice content for frozen soils.<br>“trained unified &amp; testing 3 models.xlsx”: the training dataset were first used to build the pedotransfer functions for three parameters of the unified model (results in sheets “training-unfrozen” and “training-frozen”). The testing dataset were then used to evaluate the three models (results in sheets “testing-unfrozen” and “testing-frozen”).Columns:“fr_cr”:the critical volume fraction;“ts”: the scaling exponent;“alpha”: the compensating factor;“volume water content”: initial water content at the onset of freezing;<br>Units:measured temperature in [°C];dry bulk density in [kg m^-3];porosity in [m³ m^-3];volume water content in [m³ m^-3];measured/predicted thermal conductivity in [Wm^-1°C^-1].
