JavaScript appears to be disabled on this computer. The UVI is an international standard index that describes the level of solar UV radiation on the earths surface. The index ranges from 0 to 11+ and the values are grouped into various exposure categories. INTERSUN, WHO's Global UV project, has developed and introduced an internationally agreed communication concept to ensure uniformity of sun protection messages, to facilitate the delivery of a simple and relevant message and to improve its use as an educational tool. In 2022, a new mobile phone application that provides localized information on ultraviolet (UV) radiation levels has been launched by the World Health Organization (WHO), the World Meteorological Organization (WMO), the United Nations Environment Programme (UNEP) and the International Labour Organization (ILO).[25]. The specified UV Index values serve as a benchmark for a typical atmospheric condition at each respective location. The UV Index is an important vehicle to raise public awareness of the risks of excessive exposure to UV radiation, and to alert people about the need to adopt protective measures. Vulnerable groups Children are particularly sensitive to UV radiation and require special protection. While the smaller wavelength UVC rays often only impact the top layer of our skin, UVA rays can deeply penetrate every layer of the skin, capable of causing cellular disruption in the deepest dermis layer (5).

This indicator provides state-level data on laws regarding sunscreen use in schools and indoor tanning restrictions for individuals younger than 18 years. The ultraviolet index, or UV index, is an international standard measurement of the strength of the sunburn-producing ultraviolet (UV) radiation at a particular place and time. The index is a scale of 0 to 16+, with 0 representing minimal UV exposure risk and values higher than 11 posing an extreme risk. In 2007, the United Nations honored UV index inventors Kerr, McElroy, and Wardle with the Innovators Award for their far-reaching work on reducing public health risks from UV radiation. sun-safe activities is a great way to reduce your risk of developing skin cancer. The Global Solar UV Index (UVI) described in this document is a simple measure of the UV radiation level at the Earths surface and an indicator of the potential for skin damage. UV radiation reaching the Earth's surface is largely composed of UVA with a small UVB component. UV levels UV Index and why could it break Thus, for convenience, the DUV is divided by 25mW/m2 to produce an index[13][14] nominally from 0 to 11+, though ozone depletion is now resulting in higher values. If outdoors, seek shade and wear sun-protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. The UV index values are grouped into five Predictions are made by a computer model that accounts for the effects of sun-earth distance, solar zenith angle, total ozone amount, tropospheric aerosol optical depth, elevation, snow/ice reflectivity and cloud transmission, all of which influence the amount of UV radiation at the surface.[6]. Average Sea Surface Temperature (AVHRR, 1985-97), Sea Surface Temperature (AVHRR, 1981-2006), Sea Surface Temperature Anomaly (AMSR-E, 2002-11), Sea Ice and Snow Extent, Northern Hemisphere, Sea Ice Concentration and Snow Extent, Global, What Climate Change Means for Glaciers, Storms, Fires, Clouds, and More. UV index The higher the UV index, the more intense the radiation and the greater the risk of skin damage. Unsurprisingly, climate change is not having a positive effect on skin cancer trends around the world. It can help individuals make healthy choices. The UV Index scale ranges from a low of zero to a high of 11+ in Canada, The highest values occur in southern Ontario, where values of 11, or even 12 on rare occasions, have occurred. So, it seems that changes to our personal, cultural, and global habits and values need to be made to turn the trend of increased skin cancer cases in the opposite direction. Over the long term, UV exposure can result in premature aging, skin cancer, and damage to your eyes. (Also note the huge increase in sunburn damage caused by the shorter wavelengths; e.g., for the same irradiance, 305nm is 22% as damaging as 295nm, and 325nm is 0.3% as damaging as 295nm.)

Sunlight/UV Vulnerability and Preparedness Tracking sunlight and UV exposures in a standard way can help us identify regions of high exposure and to track trends over time. The Global Solar UV Index (UVI) is a simple measurement of the UV radiation level at the Earth's surface. There is also evidence that UV radiation reduces the effectiveness of the immune system. National Weather Service provides the following UVIndex archives: The UV Index provides a forecast of the expected risk of overexposure to UV radiation from the sun. UV levels [9][10] There are some older formulas for the spectrum, resulting in differences of up to 2%. WebThis indicator provides state and county level data on monthly and annual average doses of UV irradiance measured daily and at noon. [3] Public health organizations recommend that people protect themselves (for example, by applying sunscreen to the skin and wearing a hat and sunglasses) if they spend substantial time outdoors when the UV index is 3 or higher; see the table below for more detailed recommendations. Revealed: The Travel Hotspots That Could Be Damaging [14], After sporadic attempts by various meteorologists to define a "sunburn index" and growing concern about ozone depletion, Environment Canada scientists James B. Kerr, C. Thomas McElroy, and David I. Wardle invented the modern UV index in Toronto, Ontario. The UVI is a measure of the level of UV radiation. Simple precautions will prevent both short-term and long-term damage of UV radiation exposure, while still making the time spent outdoors enjoyable. However, additional research is necessary to substantiate this.
