Ozone plays a very important role in our atmosphere because it protects any living
organisms at the Earth's surface against the harmful solar UVB and UVC radiation. In the …

The UV Index was introduced in Canada in 1992 in response to growing concerns about the
potential increase of ultraviolet (UV) radiation due to ozone depletion. The index was …

The spectral albedo of the earth's surface, ie the ratio between spectral irradiance reflected
by the ground to all directions and global irradiance, was measured by a spectroradiometer …

Solar ultraviolet-B (UV-B) radiation has played a crucial role in the evolution of life on Earth.
UV exposure presents both risks and benefits to humans. Optimal UV-B exposure behaviors …

One of the main concerns regarding a decrease in stratospheric ozone is the consequential
increasein the amount of ultraviolet (UV) radiation that reaches the lower atmosphere and …

In August 2021, a historic heatwave was recorded in Greece which resulted in extreme
wildfire events that strongly affected the air quality over the city of Athens. Saharan dust was …

Five Dobson and two Brewer spectrophotometers were used for total ozone observations at
Arosa, beginning in 1926 and providing the world's longest series. In this paper we present …

Both Brewer and Dobson Spectrophotometers have been taking routine simultaneous direct‐
Sun total ozone measurements from the five stations in the Canadian ozone monitoring …

The clear sky UV-index is expressed as a function of two predictable quantities: the solar
zenith angle and total ozone. This function is derived by fitting the measurements of total …

This article focuses on the comparison of the total ozone column data from the Ozone
Monitoring Instrument (OMI) flying aboard the NASA EOS‐Aura satellite platform with ground …
