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).

这项研究是1972年以来所进行研究的继续和扩展，其目的是监测太阳系外行星和卫星沿着相关比较星的亮度，以便（1）确定太阳光度的上限或探测太阳光度的变化;（2）研究这些天体的特性，包括季节和气候效应;研究大气透明度的自然变化，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成果是发现了明确的证据，证明行星大气的全球状态和可变的太阳紫外线输出之间存在直接的相互作用。这些影响与怀疑的影响相似，并试图作为可能的太阳气候影响的输入。因此，这项工作对于太阳辐照度变化（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。
