The Minnaert function, or Minnaert profile, is a mathematical model used in the study of planetary atmospheres, particularly in the field of planetary science and astronomy. It describes the variation in brightness of a celestial body as a function of the solar zenith angle, which is the angle between the sun's rays and the normal (perpendicular) to the surface of the body being observed.
