- To calculate the UV Index, you need to consider several factors12:
- The thickness of the ozone layer over your city (detected using satellites).
- The cloud cover over your city (clouds block UV radiation to varying degrees).
- The time of year (in winter, UV radiation is lower than in the summer because of the sun's angle).
- The elevation of your city (higher elevations get more UV radiation).

science.howstuffworks.com/nature/climate-weather…The UV index measures the intensity of ultraviolet (UV) radiation from the sun at a location. It’s calculated using the latitude and altitude of that place, time of day, time of year, ground conditions, cloud cover and state of the ozone layer in the atmosphere.www.skincancer.org/blog/the-uv-index-know-your-ri…The UV Index value is determined by dividing the dose rate (milliWatts per square meter) by the standard of 25 milliWatts per square meter. This results in a number that usually ranges from 0 (where there is no sun light) to the mid 'teens.www.cpc.ncep.noaa.gov/products/stratosphere/uv_… - People also ask
