Calculate fruit surface temperature

Description

Calculate fruit surface temperature

Usage

fruit_surface_temp(
  t_air,
  wind_speed,
  s_rad,
  t_dew,
  t_ground = t_air,
  ground_emissivity = 0.97,
  fruit_diameter = 0.08,
  fruit_emissivity = 0.95,
  fruit_reflectance = 0.6,
  fruit_sunlit_prop = 1,
  fruit_groundlit_prop = 0,
  fruit_surface_conductance = 5e-05,
  print_all_vars = FALSE,
  possibly = FALSE
)

Arguments

t_air	Air temperature (°C)
wind_speed	Wind speed (m/s)
s_rad	Solar radiation (W/m^2)
t_dew	Dew point temperature (°C)
t_ground	Ground temperature (°C), defaults to air temperature
ground_emissivity	Ground emissivity, default 0.97
fruit_diameter	Fruit diameter (m), default 0.08 meters
fruit_emissivity	Fruit emissivity, default 0.95
fruit_reflectance	Fruit reflectance, default 0.6
fruit_sunlit_prop	Proportion of fruit area exposed to sunlight, default 1 for fully exposed fruit
fruit_groundlit_prop	Proportion of fruit area exposed to longwave radiation emitted from ground, default 0 for ground shaded fruit
fruit_surface_conductance	Fruit surface conductance to water vapor diffusion (m/s), default 5E-5 m/s
print_all_vars	Prints all energy balance components if TRUE, default FALSE
possibly	if TRUE returns NA when energy balance can't be solved likely due to invalid coefficients, useful for debugging. Default FALSE

Value

Fruit surface temperature (°C)

Examples

fruit_surface_temp(t_air = 33, wind_speed = 1, s_rad = 800, t_dew = 30)
