自环境卫星平台出现以来，白天测量可见光谱中的反射阳光一直是地球观测辐射计的主要内容。在夜间，这些相同的光谱传感器传统上仅限于热红外发射，其中包含的许多重要天气和气候参数的信息内容相对较少。这些缺陷限制了我们描述与改进天气和气候过程监测、理解和建模相关的参数的完整昼夜行为和过程的能力。可见光谱光信息确实存在于夜间，来源广泛，但其检测需要专门的技术。美国国防部卫星上已经以有限的方式进行了此类测量，但携带新型日/夜波段（DNB）辐射计的 Suomi 国家极地轨道合作伙伴（NPP）卫星首次提供了夜间可见光和近红外光的定量测量。在这里，我们展示了 DNB 为夜间微光可见光应用带来的扩展潜力。通过地面和地外光源的结合，这样的观测总是可用的——扩展了许多当前的现有应用，同时实现了全新的功能。这些新颖的微光测量为大量新的跨学科研究课题打开了大门，同时为后续基于卫星的微光可见光传感器的优化设计开辟了道路。
Daytime measurements of reflected sunlight in the visible spectrum have been a staple of Earth-viewing radiometers since the advent of the environmental satellite platform. At night, these same optical-spectrum sensors have traditionally been limited to thermal infrared emission, which contains relatively poor information content for many important weather and climate parameters. These deficiencies have limited our ability to characterize the full diurnal behavior and processes of parameters relevant to improved monitoring, understanding and modeling of weather and climate processes. Visible-spectrum light information does exist during the nighttime hours, originating from a wide variety of sources, but its detection requires specialized technology. Such measurements have existed, in a limited way, on USA Department of Defense satellites, but the Suomi National Polar-orbiting Partnership (NPP) satellite, which carries a new Day/Night Band (DNB) radiometer, offers the first quantitative measurements of nocturnal visible and near-infrared light. Here, we demonstrate the expanded potential for nocturnal low-light visible applications enabled by the DNB. Via a combination of terrestrial and extraterrestrial light sources, such observations are always available-expanding many current existing applications while enabling entirely new capabilities. These novel low-light measurements open doors to a wealth of new interdisciplinary research topics while lighting a pathway toward the optimized design of follow-on satellite based low light visible sensors.
