Abstract:

Practical approximations for the Chapman function over the entire range of possible solar zenith angles are considered. The approximations are numerically evaluated for a selected number of parametric values. Comparison with the Chapman function on a percent difference basis is provided. Some practical points regarding geometry are discussed for angles exceeding pi2. Author
