Qthermal_radiation_absorbed {TrenchR}

Absorbed Thermal Radiation

Description

The function estimates longwave (thermal) radiation (W) absorbed from the sky and the ground (Campbell and Norman 1998; Riddell et al. 2018).

Usage

Qthermal_radiation_absorbed(
  T_a,
  T_g,
  epsilon_ground = 0.97,
  a_longwave = 0.965
)

Arguments

T_a

numeric air temperature (C).

T_g

numeric ground temperature (C).

epsilon_ground

numeric emissivity (proportion) for more soil types (Campbell and Norman 1998).

a_longwave

numeric absorptance (proportion) of organism to longwave radiation (Bartlett and Gates 1967; Buckley 2008).

Value

numeric thermal radiation absorbed (W).
