I_i: Global insolation on Mars inclined surface over time period

Description

Calculates the total solar energy received on an inclined surface between specified start and end times. Obtained by integrating global irradiance over the time period.

Usage

I_i(
  Ls,
  phi,
  longitude,
  tau,
  Ts_start,
  Ts_end,
  al = albedo(latitude = phi, longitude = longitude, tau = tau),
  beta,
  gamma_c
)

Value

Global insolation on inclined surface over specified time period [Wh/m²]

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

beta

Surface tilt/slope angle from horizontal [deg]

gamma_c

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