最近关于平流层臭氧消耗的报告引起了人们对到达地球表面的太阳紫外线辐射水平的关注。自1974年以来，美国建立了一个地面监测站网络，跟踪测量生物有效紫外线辐射（UVB， 290至330纳米）。1974年至1985年在地面没有检测到中波辐射的增加，这一事实表明对流层的气象、气候和环境因素在中波辐射衰减方面可能比以前所怀疑的发挥更大的作用。
Recent reports of stratospheric ozone depletion have prompted concerns about the levels of solar ultraviolet radiation that reach the earth''s surface. Since 1974 a network of ground-level monitoring stations in the United States has tracked measurements of biologically effective ultraviolet radiation (UVB, 290 to 330 nanometers). The fact that no increases of UVB have been detected at ground levels from 1974 to 1985 suggests that meteorological, climatic, and environmental factors in the troposphere may play a greater role in attenuating UVB radiation than was previously suspected.
