The UV Index was established more than 20 years ago as a tool for sun protection and
health care. Shortly after its introduction, UV Index monitoring started in several countries …

The short-and long-term variability of the surface spectral solar ultraviolet (UV) irradiance is
investigated across Italy using high-quality ground-based measurements from three …

Among the factors affecting the solar radiation that reaches the ground, clouds play a key
role in its short-term variability causing events ranging from almost total reduction to …

This study examines the wavelength dependence of cloud optical depth. To accomplish this
task two different wavelength bands of the solar spectrum were considered in the cloud …

As clouds and aerosols are the main sources of uncertainty in the determination of the
energy balance of the Earth, there is a growing interest in the evaluation of their radiative …

The coupling between oceanic and atmospheric sulfur cycles is fundamental for the
understanding of the role of sulfate particles as potential climate regulators. We discuss …

The present study is focused on the influence of atmospheric factors (ozone, aerosols,
precipitable water and, mainly, clouds) on the ratio (measured and modelled) between UV …

A blind intercomparison of ground-based ultraviolet (UV) instruments has been organized
for the first time in Italy. The campaign was coordinated by the Environmental Protection …

This paper presents a study of a strong desert dust episode over the Iberian Peninsula, and
its effect on the spectral ultraviolet (UV) irradiance in Granada, Spain. Remote sensing …

Measurements of downwelling shortwave (SW) and longwave (LW) irradiance were carried
out on an oceanographic buoy close to the island of Lampedusa (Italy), in the central …
