TrenchR (version 1.1.1)

Tsoil: Approximate Soil Temperature

Description

The function estimates soil temperature (C) at a given depth and hour by approximating diurnal variation as sinusoidal. The function is adapted from Campbell1998;textualTrenchR and described in Riddell2018;textualTrenchR.

Usage

Tsoil(T_g_max, T_g_min, hour, depth)

Value

numeric soil temperature (C).

Arguments

T_g_max

numeric daily maximum soil surface temperature (C).

T_g_min

numeric daily minimum soil surface temperature (C).

hour

numeric hour of the day.

depth

numeric depth (cm).
