Abstract
The paper introduces a method which allows the consideration of the curvature and stratification of the atmosphere when determining relative optical air mass. Formulae for relative optical air mass determination for places at sea level, at higher altitudes and for cloud formations are presented. These formulae were derived to promote further sky model development.Keywords
