Atmospheric physics radiation (emitted by the sun) and terrestrial radiation (emitted by Earth's surface and atmosphere). Solar radiation contains variety of wavelengths. Visible light has wavelengths between 0.4 and 0.7 micrometers. Shorter wavelengths are known as the ultraviolet (UV) part of the spectrum, while longer wavelengths are grouped into the infrared portion of the spectrum. Ozone is most effective in absorbing radiation around 0.25 micrometers, where UV-c rays lie in the spectrum. This increases the temperature of the nearby stratosphere. Snow reflects 88% of UV rays, while sand reflects 12%, and water reflects only 4% of incoming UV radiation. The more glancing
The Sun Is Often Out The Sun Is Often Out The Sun Is Often Out (stylized as THE SUN iS OfTEN oUT) is the debut album by Longpigs, released in 1996 on U2's record label, Mother Records.

The third single - "Far" fared a little better, scraping into the Top 40, reaching No. 37 and received significant radio airplay, particularly on the national pop and rock radio station, BBC Radio 1.
