  abstract = {{A} single-frequency dielectric model for thawed and frozen {A}rctic organic-rich (80%-90% organic matter) soil was developed. {T}he model is based on soil dielectric data that were measured over the ranges of volumetric moisture from 0.007 to 0.573 cm(3)/cm(3), dry soil density from 0.564 to 0.666 g/cm(3), and temperature from 25 degrees {C} to -30 degrees {C} (cooling run), at the frequency of 1.4 {GH}z. {T}he refractive mixing model was applied to fit the measurements of the soil's complex refractive index ({CRI}) as a function of soil moisture, with the values of temperature being fixed. {U}sing the results of this fitting, the parameters of the refractive mixing model were derived as a function of temperature. {T}hese parameters involve the {CRI}s of soil solids as well as bound, transient, and free soil water components. {T}he error of the dielectric model was evaluated by correlating the predicted complex relative permittivity ({CRP}) values of the soil samples with the measured ones. {T}he coefficient of determination ({R}-2) and the root-mean-square error ({RMSE}) were estimated to be {R}-2 = 0.999, {RMSE} = 0.27 and {R}-2 = 0.993, {RMSE} = 0.18 for the real and imaginary parts of the {CRP}, respectively. {T}hese values are in the order of the dielectric measurement error itself. {T}he proposed dielectric model can be applied in active and passive remote-sensing techniques used in the areas with organicrich soil covers, mainly for the {SMOS}, {SMAP}, and {A}quarius missions.},
