UVI

Ultraviolet Index (UVI) is a unitless scale that indicates the level of ultraviolet radiation from the sun reaching the Earth's surface. Developed by meteorologists and health agencies, the UVI helps the public assess the potential risk of sun exposure and take protective measures. The scale ranges from 0 to 11+, with categories such as low (0–2), moderate (3–5), high (6–7), very high (8–10), and extreme (11+). UVI values are affected by solar elevation, latitude, altitude, ozone concentration, cloud cover, and surface reflection. Forecasts and real-time measurements are provided by weather agencies and satellite-based instruments. Practical guidance accompanies the UVI, including sunscreen use, protective clothing, sunglasses, and shade during peak sun hours.
