Show moreModels of atmospheric transmission allow the estimation of spectral and biologically-weighted ultraviolet (UV) radiation reaching the Earth’s surface. The theory of radiative transfer is well established, but information about the atmosphere (e.g., ozone profiles, cloud morphology), which is required as input to the models, is often incomplete. Still, model sensitivity studies provide many useful insights that, when combined with measurements, give us a more complete understanding of the complex UV environment. Show less
