WebThe Global Solar UV Index (UVI) is a simple measurement of the UV radiation level at the Earth's surface. WebUV Index worldwide. It cannot be simply related to the irradiance (measured in W/m2) because the UV of greatest concern occupies a spectrum of wavelengths from 295 to 325nm, and shorter wavelengths have already been absorbed a great deal when they arrive at the earth's surface. However, sunscreen represents a last line of defence, and should never be used to prolong the duration of sun exposure. Altitude: at higher altitudes, a thinner atmosphere absorbs less UV radiation.Ozone: ozone absorbs some of the UV radiation that would otherwise reach the Earth's surface. Over the long term, UV exposure can result in premature aging, skin cancer, and damage to your eyes. The UV Index does not drop below 11 at any point in the year, which means that there is a constant and extreme risk of harm. The UVI gives an indication of the level of UV radiation and the potential danger of sun exposure. Imagery produced by the NASA Earth Observations team based on data provided by Jerry Ziemke from the Ozone Monitoring Instrument (OMI) science team. Even for very sensitive fair-skinned people, the risk of short-term and long-term UV damage below a UVI of 2 is limited, and under normal circumstances no protective measures are needed. Moderate mean UVI values occur between 30 and 48 N and high UVI south of 35 N. Additionally, very high mean UVI up to 7.8 are detected south of 32 N. Figure 3. Increasing time spent in the shade, checking your local areas UV index regularly, and reducing your time intentionally sun tanning are all great steps for everyone to take to prevent sunburns and skin damage from the sun. WebThe monthly average maps use the same color scale and class breaks as the annual average map for the contiguous United States for the purpose of showing monthly variation relative to the annual average. UV Index It serves as an important vehicle to raise public awareness and to alert people about the need to adopt protective measures when exposed to UV radiation. The UV-Index. What is the coldest month in Auckland? However, higher UV Index values Moderate mean UVI values occur between 30 and 48 N and high UVI south of 35 N. Additionally, very high mean UVI up to 7.8 are detected south of 32 N. Figure 3. February. WebThe UV index climatology shows how much UV exposure a person could get on average during each month. Africa; May. So as we can see, the top 20 countries are quite dispersed across the globe. TheGlobal Solar UV Index is intended to be used by national and local authorities and non-governmental organizations active in the area of skin cancer prevention, as well as meteorological offices and media outlets involved with UVI reporting. Tracking sunlight and UV exposures in a standard way can help us identify regions of high exposure and to track trends over time. Table 1 shows the average monthly UV Index across Australia. The levels of UV radiation and therefore the values of the index vary throughout the day. Haze in the atmosphere can even increase UV radiation exposure.

Countries close to the equator can experience very high UV levels in the middle of the day throughout the year.
