- 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).
