Matches the sun's height above the horizon, which drives UV strength. The UV figures are clear-sky estimates at sea level with typical ozone; cloud and haze lower the real value. Altitude adds about 10% per 1,000 m. Reflection adds about 10% near water, 15% on sand and around half again on fresh snow. These adjustments are estimates.
