G_ali: Albedo-reflected irradiance on Mars inclined surface

Description

Calculates the solar irradiance reflected from the Martian surface (ground-reflected radiation) incident on an inclined surface. Accounts for the view factor of the ground from the tilted surface.

Usage

G_ali(
  Ls,
  phi,
  longitude,
  Ts,
  z = Z(Ls = Ls, Ts = Ts, phi = phi),
  tau,
  al = albedo(latitude = phi, longitude = longitude, tau = tau),
  beta
)

Value

Albedo-reflected irradiance on inclined surface [W/m²]

Arguments

Ls

Areocentric longitude [deg]

phi

Planetary latitude [deg]

longitude

Planetary longitude [deg]

Ts

Solar time [h]

z

Sun zenith angle [deg]. If not provided, calculated from Ls, phi, and Ts

tau

Atmospheric optical depth (dimensionless)

al

Surface albedo (dimensionless, 0-1). If not provided, calculated from latitude, longitude, and tau

beta

Surface tilt/slope angle from horizontal [deg]
