- •
A generalized expression for the geometrical correction for shadow- bands is proposed.
- •
Total correction models have been reformulated to be used on any measurement plane.
- •
A new statistical estimator for models’ performance analysis is proposed: μ1-α.
- •
10-min measurements and models’ estimations on 4 vertical planes have been compared.
- •
Results can be extended to any shadow-band radiometer system.
