The project will be a ?proof of concept? for a new instrument platform called the Autonomous Arctic Infrared Observer (AAIRO). The primary goal is to assess the value of data products retrieved from simulated AAIRO measurements relative to instruments that are currently deployed as part of the ICECAPS experiment. [ICECAPS stands for Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit.] A computer model will be developed that simulates the operation of the AAIRO by degrading the spectral resolution of spectra from the Polar Atmospheric Emitted Radiance Interferometer (P-AERI) deployed at Summit, Greenland. Algorithms will be used to retrieve atmospheric properties from the simulated AAIRO spectra. Retrieved properties will include near-surface temperature structure, trace gas amounts of water vapor, carbon monoxide, and methane, and macrophysical (fraction, base height) and microphysical properties (phase, effective particle radius, optical depth) of clouds. Retrieved properties from the AAIRO simulator will be compared to those retrieved from the suite of ICECAPS instruments. This project will prove the usefulness of the AAIRO as a complementary instrument within the broader context of NSF?s Arctic Observing Network and will set the stage for future development of the actual AAIRO instrument. A graduate student and a postdoctoral fellow who will have the opportunity to be involved in both infrared instrument design and remote sensing retrievals. Proof of the AAIRO?s measurement capabilities could potentially improve the polar research community?s ability to address the basic science questions outlined in the SEARCH Implementation Plan. The potential development of an instrument like that AAIRO complements other existing and proposed sensors and could provide a more complete network of observations that are critical for understanding the Arctic system.

该项目将是一个“概念验证”？一个名为自主北极红外观测仪（AAIRO）的新仪器平台。主要目标是评估从模拟 AAIRO 测量中检索到的数据产品相对于当前作为 ICECAPS 实验一部分部署的仪器的价值。 [ICECAPS 代表 Summit 能量、云、大气状态和降水的综合表征。] 将开发一个计算机模型，通过降低部署在格陵兰岛 Summit 的极地大气发射辐射干涉仪 (P-AERI) 的光谱分辨率来模拟 AAIRO 的运行。算法将用于从模拟的 AAIRO 光谱中检索大气特性。检索到的属性将包括近地表温度结构、水蒸气、一氧化碳和甲烷的痕量气体量，以及云的宏观物理属性（分数、基础高度）和微观物理属性（相位、有效粒子半径、光学深度）。从 AAIRO 模拟器检索的属性将与从 ICECAPS 仪器套件检索的属性进行比较。该项目将证明 AAIRO 作为 NSF 北极观测网络更广泛背景下的补充仪器的有用性，并将为实际 AAIRO 仪器的未来发展奠定基础。 一名研究生和一名博士后，将有机会参与红外仪器设计和遥感检索。 AAIRO 测量能力的证明可能会提高极地研究界解决 SEARCH 实施计划中概述的基础科学问题的能力。像 AAIRO 这样的仪器的潜在发展可以补充其他现有和拟议的传感器，并可以提供更完整的观测网络，这对于了解北极系统至关重要。
