The sun has the highest altitude angle in summer, so the ultraviolet radiation in summer is significantly higher than in other seasons. The ultraviolet aging test chamber is related to simulation. At noon, the sun is directly on the ground, and at this time, the ultraviolet radiation is strongest in a day.
Does the UV become stronger as the temperature rises? Shen Yuanfang, a researcher at the Chinese Academy of Meteorological Sciences, told reporters that the UV aging test chamber is not directly related to the temperature. The intensity of ultraviolet rays depends on the altitude angle of the sun. The higher the sun in the sky, the higher the level of ultraviolet radiation.
At higher altitudes, the atmosphere is relatively thinner and the ultraviolet light absorbed is relatively less, so people on the Qinghai-Tibet Plateau always hang "red faces." Shen Yuanfang told reporters that the underlying surface also affects the strength of ultraviolet radiation. Grass, soil and water reflect approximately 10% of ultraviolet radiation; dry beach sand reflects approximately 15% of ultraviolet radiation, and sea foam reflects approximately 25%; fresh snow Up to 80% reflection. Therefore, although the solar altitude angle in winter is smaller than that in summer, the reflection of ultraviolet rays by snow will greatly increase the amount of radiation.
It is not difficult to find that the ultraviolet aging test chamber has a close relationship between ultraviolet rays and clouds. The sun shines vertically on the ground, and the distance of ultraviolet rays passing through the clouds is the shortest and the least is absorbed, so the most ultraviolet rays passing through the clouds. Although the clouds can absorb ultraviolet rays, up to 80% of the ultraviolet radiation can still penetrate the thin clouds, and the mist in the atmosphere can even increase the intensity of the ultraviolet radiation, so cloudy weather must also be "sun protection."
