Diffuse daily insolation on Mars horizontal surface

Calculates the diffuse solar energy (scattered by atmospheric dust) received over a full Martian day on a horizontal surface. Obtained by integrating diffuse irradiance from sunrise to sunset.

Usage

H_dh(
  Ls,
  phi,
  longitude,
  tau,
  al = albedo(latitude = phi, longitude = longitude, tau = tau)
)

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

Value

Diffuse daily insolation [Wh/m²-day]
