R Documentation

Absorbed Solar and Thermal Radiation

Description

The function estimates solar and thermal radiation (W) absorbed by the surface of an animal following \insertCiteGates1980TrenchR and \insertCiteSpotila1992TrenchR.

Usage

Qradiation_absorbed(
  a = 0.9,
  A,
  psa_dir,
  psa_dif,
  psa_ref,
  S_dir,
  S_dif,
  S_ref = NA,
  rho = NA
)

Arguments

`a`	`numeric` solar absorptivity of animal surface (proportion), default value is for reptiles (0-1).
`A`	`numeric` surface area (m²).
`psa_dir`	`numeric` proportion surface area exposed to direct solar radiation (0-1).
`psa_dif`	`numeric` proportion surface area exposed to diffuse solar radiation (0-1).
`psa_ref`	`numeric` proportion surface area exposed to reflected solar radiation (0-1).
`S_dir`	`numeric` direct solar radiation (W m^-2).
`S_dif`	`numeric` diffuse solar radiation (W m^-2).
`S_ref`	`numeric` reflected solar radiation (W m^-2), either provided or estimated if surface albedo is provided instead
`rho`	`numeric` is surface albedo (proportion), optional (not used) if reflected radiation is provided. Values available in \insertCiteGates1980TrenchR Table 8.2.

Value

numeric solar radiation absorbed (W)
