Calculates the ground-reflected solar energy received over a full Martian day on an inclined surface. Obtained by integrating albedo-reflected irradiance from sunrise to sunset.

Usage

H_ali(
  Ls,
  phi,
  longitude,
  tau,
  al = albedo(latitude = phi, longitude = longitude, tau = tau),
  beta,
  gamma_c
)

Arguments

Ls

Areocentric longitude [deg]

phi

Planetary latitude [deg]

longitude

Planetary longitude [deg]

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]

gamma_c

Surface azimuth angle [deg]. Zero facing equator, east negative, west positive (-180 to +180)

Value

Albedo-reflected daily insolation on inclined surface [Wh/m²-day]
