Measurements of solar radiation made at Mauna Loa, Hawaii, over a period of 13 years give no evidence that human activities affect atmospheric turbidity on a global scale. Short-term fluctuations in insolation appear to be associated with naturally produced tropospheric aerosols. The intrusion of volcanic dust into the stratosphere results in prolonged increases in atmospheric opacity due to the extended residence times of aerosols in the stratosphere.
在夏威夷莫纳罗亚进行的长达13年的太阳辐射测量结果表明，没有证据显示人类活动在全球范围内影响大气浑浊度。日照的短期波动似乎与自然产生的对流层气溶胶有关。火山尘埃侵入平流层会导致大气透明度长期增加，这是因为气溶胶在平流层中的停留时间延长。
