title: Ratio measurement of diffuse to direct solar irradiances in the middle ultraviolet.
abstract: The experimental details in the ratio measurement of diffuse to direct solar irradiances in the middle uv are described. Some experimental data for typical partly cloudy inland summer weather in Florida are discussed and compared with various theoretical calculations. The more extensive data for clear days from P. Bener are also compared with various calculations. We have concluded that it is feasible to improve the uv calculations with the proposed ratio measurements for various sky conditions.
