soil_temperature_integrand {TrenchR}R Documentation

Solve Equation for Soil Temperature

Description

This function is called by soil_temperature_equation to solve the equation for soil temperature from Beckman et al. (1973). The function represents the integrand in the equation. It is not intended to be called directly.

Usage

soil_temperature_integrand(x, L, z0)

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.

L

numeric Monin-Obukhov length, a measure of the instability of heat flow (Beckman et al. 1973).

z0

numeric surface roughness (m).

Value

numeric integrand for soil temperature function.
