Solar and Planetary Variations and Atmospheric Transparency

这项研究是自1972年以来开展的研究的延续和扩展，其目的是监测外太阳系行星和卫星及其相关比较恒星的亮度，以便：(1)设定太阳亮度变化的上限或探测太阳亮度变化；(2)研究这些尸体的性质，包括季节和气候影响；(3)研究大气透明度的自然变率，包括火山活动对大气的长期影响，以及可能的人为影响。这项工作的一个重要结果是发现了行星大气总体状态与可变太阳紫外线输出之间直接相互作用的明确证据。这些影响与那些被怀疑并被寻求作为可能的太阳气候影响输入的影响相似。因此，这项工作对太阳辐照度变化（气候变化）、太阳紫外线变化（大气光化学）和大气气溶胶观测（火山）方面的日地关系非常重要。

The aim of this study, which is a continuation and extension of studies carried out since 1972, is to monitor the brightnesses of planets and satellites in the outer solar system along with their associated comparison stars in order to (1) set an upper limit to, or to detect, variability of the luminosity of the Sun; (2) study the properties, including seasonal and climate effects, of these bodies; and (3) study the natural variability of atmospheric transparency, including the long-lived effects of volcanism on the atmosphere, as well as possible anthropogenic influences. One important result of this work has been the discovery of clear evidence for a direct interaction between the global state of a planetary atmosphere and variable solar uv output. These effects are similar to the ones suspected and sought as inputs to possible solar-climate effects. Thus the work is important to sun-earth relationships in terms of changes in solar irradiance (climate change), variability in solar uv (atmospheric photochemistry) and observations of atmospheric aerosols (volcanoes).
