The Ultraviolet Index Is Well Estimated by the Terrestrial Irradiance at 310 nm

Sensors, 2021
Ultraviolet (UV) exposure significantly contributes to non-melanoma skin cancer. In the context of health, UV exposure is the product of time and the UV Index (UVI), a weighted sum of the irradiance I(λ) over all wavelengths from λ = 250 to 400 nm.
