altitude_azimuth

[-ang] A tuple corresponding to altitude and azimuth angle.This input can be used instead of specifying the monthDayTime.

ground_reflect

[-g rfl] A float number to indicate ground reflectance.

latitude

[-a lat] A float number to indicate site altitude. Negative angle indicates south latitude.

longitude

[-o lon] A float number to indicate site latitude. Negative angle indicates east longitude.

meridian

[-m mer] A float number to indicate site meridian west of

Greenwich.
