Calculates the diffuse solar energy (scattered by atmospheric dust) received on a horizontal surface between specified start and end times. Computed as difference between global and beam insolation.

Usage

I_dh(
  Ls,
  phi,
  longitude,
  tau,
  Ts_start,
  Ts_end,
  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)

Ts_start

Start of integration period [h]

Ts_end

End of integration period [h]

al

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

Value

Diffuse insolation over specified time period [Wh/m²]
