soil_conductivity: Soil Thermal Conductivity

In trenchproject/TrenchR: Tools for Microclimate and Biophysical Ecology

Soil Thermal Conductivity

Description

The function estimates soil thermal conductivity (W m^-1 K^-1) using the methods of \insertCitedeVries1963;textualTrenchR.

Usage

soil_conductivity(x, lambda, g_a)

Arguments

x	numeric vector of volume fractions of soil constituents (e.g., clay, quartz, minerals other than quartz, organic matter, water, air). The volume fractions should sum to 1. Note that x and lambda values in the example correspond to these soil constituents.
lambda	numeric vector of the thermal conductivities (W m-1 K-1) of the soil constituents.
g_a	numeric shape factor on soil particles. The soil particles are assumed to be ellipsoids with axes g_a, g_b, and g_c, where g_a + g_b + g_c = 1 and g_a = g_b. \insertCitedeVries1952;textualTrenchR suggests g_a = g_b = 0.125.

Value

numeric soil thermal conductivity (W m^-1 K^-1).
