The nephelometer experiment carried on the Galileo probe was designed to measure the jovian cloud structure and its microphysical characteristics from entry down to atmospheric pressure levels greater than 10 bars. Before this mission there was no direct evidence for the existence of the clouds below the uppermost cloud layer, and only theoretical models derived from remote sensing observations were available for describing such clouds. Only one significant cloud structure with a base at about 1.55 bars was found along the probe descent trajectory below an ambient pressure of about 0.4 bar, although many indications of small densities of particle concentrations were noted during much of the descent.
伽利略探测器上进行的浊度计实验旨在测量木星云层结构及其微观物理特征，测量范围从进入大气层到气压大于10巴的高度。在此次任务之前，没有直接证据表明在最上层云层之下存在云层，只有从遥感观测得出的理论模型可用于描述此类云层。在探测器下降轨迹上，在环境压力约为0.4巴以下，仅发现一个显著的云层结构，其底部约在1.55巴处，不过在大部分下降过程中都注意到了粒子浓度低密度的许多迹象。
