The amounts of UV one is exposed to also varies with altitude. As a rule of thumb, UV levels increase about 4% for every 1,000 foot gain in altitude. This increase has nothing to do with being closer to the sun - any elevation you might gain would be miniscule in comparison to the distance from the earth to the sun, and so would have an insignificant outcome on UV levels.

A thinner atmosphere is the primary reason for this, as there are fewer particles to absorb UV. At low altitudes, the presence of tropospheric ozone (smog), aerosols, and other substances such as dust reduce the UV-B levels that reach the ground. Solar UV radiation increases with altitude mainly due to decreasing amounts of air molecules, ozone, aerosols, and clouds in the atmosphere as well as due to snow covered surfaces. The altitude thus increase total UV radiation levels. ALTITUDE At higher altitudes, a thinner atmosphere absorbs less UV radiation. With every 1000 metres increase in altitude, UV radiation levels increase by 10% to 12%. OZONE Ozone absorbs some of the UV radiation that would otherwise reach the Earth’s surface.

However, the sides of clouds can also reflect UV and increase the amount of Ultraviolet (UV) light with wavelengths between 240 and 320 nm is absorbed by the stratosphere to increase with altitude, giving rise to the inversion layer that One can observe that the photodissociation ratio of O2 increases quantitively and rises slightly in altitude; in other words, the Rayleigh diffusion improves the High elevation mountain and hillside vineyards tend to receive more direct and concentrated sunlight – for every 1,000 feet gain in elevation, the level of UV rays Jul 10, 2019 Altitude: More UV rays reach the ground at higher elevations. sand, snow, pavement, or even grass, leading to an increase in UV exposure.

in the mountains) the air is cleaner and the thinner, and atmosphere absorbs less UV radiation. UV levels increase by After calculating the clear sky UV Index for 1AU at sea level (UVI0 (ozone, SZA)), ozone column are combined, the increases with altitude are nearly linear). Aug 7, 2019 that for every 1,000′ you gain in elevation, the sun's rays can intensify by around 4%. This means that compared to sea level, Colorado's UV The division between UVB and UVC is chosen as 290 nm since ultraviolet Altitude. In general, each 1 km increase in altitude increases the ultraviolet flux by Mar 25, 2016 also has one sizeable health drawback—an increased risk for skin cancer.

UV radiation has a significant increase with the altitude. We propose a new method for calculating the altitude UV dependence for different types of biologically active UV radiation. The increase in UV exposure with altitude shown here may help explain the increase in melanoma incidence with altitude, whereas the increase in irradiance with altitude leads to the incorrect conclusion that UV radiation plays a minor role for the altitude-related melanoma incidences. The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the earth's surface.

ent geophysical parameters in UV variations with altitude. The decrease in molecular number density, especially at high altitudes, and the increase in surface albedo play the most signiﬁcant role in the UV growth.

Not only is there extra UV exposure, but if a person’s eyes are not protected, they are at risk of photokeratitis, or an eye sunburn. This is a 35% increase compared to a corresponding snow‐free surface.
