Moreover, snow and sand can reflect sunlight. Local air quality can affect our daily lives. Uv index today by zip code location and hourly burning time forecast. Ozone is a gaseous pollutant and key component of smog, formed when sunlight or solar ultraviolet radiation causes nitrogen oxides (nox) and volatile organic compounds (vocs) to react. The air quality index is based on measurement of particulate matter (pm2.5 and pm10), ozone (o3), nitrogen dioxide (no2), sulfur dioxide (so2) and carbon monoxide (co) emissions.
The higher the index, the more intense and dangerous to your health the solar radiation is. This daily prediction is a calculation of five data elements that depict the amount of ultraviolet radiation impacting the surface (1 m 2) at solar noon. The ultraviolet application gives you the information that lets you know when the level of solar uv radiation is predicted to be unusually high, and consequently the risk of overexposure is greater. Find out how much uv protection you'll need for your outdoor activities and sports. Epa and nws report the index.
