Understanding the changing Arctic climate requires detailed knowledge of the spatial and radiative properties of Arctic clouds. However, quantifying the relationships between cloud temporal and spatial distribution and radiative impacts requires more continuous and accurate measurements. Important gaps in the capabilities of current satellite- and ground-based cloud sensors can be filled with an Arctic network of ground-based long-wave infrared cloud imagers. This project will deploy an Infrared Cloud Imager (ICI) to measure the spatial and temporal distribution and optical properties of Arctic clouds continuously (day and night) for a full annual cycle at Barrow, Alaska, while also developing a new, compact version of this unique instrument that will enable future operation of a network of autonomous cloud sensors throughout the non-coastal Arctic. ICI data will enable many studies on relationships such as cloud spatial-temporal variability and cloud radiative forcing. Broader impacts will include providing an immediately valuable data stream in a cross-agency cooperation between the NSF and the Department of Energy (DOE), helping to establish the long-needed capability of diurnal cloud amount measurements at the North Slope of Alaska facility in Barrow, Alaska, and providing unique cross-disciplinary training of graduate and undergraduate students in engineering and science.

要了解北极气候的变化，需要对北极云的空间和辐射特性有详细的了解。然而，量化云的时间和空间分布与辐射影响之间的关系需要更连续和准确的测量。目前卫星和地面云传感器能力方面的重大差距可以通过北极地面长波红外云成像仪网络来填补。该项目将在阿拉斯加的巴罗部署一台红外云成像仪，连续（昼夜）测量北极云的空间和时间分布以及光学特性，同时还将开发这一独特仪器的一个新的紧凑型版本，使整个非沿海北极地区的自主云传感器网络能够在未来运行。ICI数据将使云的时空变率和云辐射强迫等关系的许多研究成为可能。更广泛的影响将包括在美国国家科学基金会和能源部（DOE）之间的跨机构合作中提供立即有价值的数据流，帮助在阿拉斯加北坡设施建立长期需要的昼夜云量测量能力位于阿拉斯加州巴罗的设施，并为工程和科学领域的研究生和本科生提供独特的跨学科培训。
