云冰通过与大气辐射、动力学、能量和降水过程的相互作用，在地球气候和天气系统中发挥重要作用。200-1000 GHz的亚毫米波（submm）遥感能够提供可见光（维斯）/红外（IR）和低频微波（MW）传感器（10-183 GHz）所不能提供的灵敏度，并且能够测量对流层中上部的云冰。IceCube 883-GHz云辐射计是美国宇航局为提高亚毫米波接收器技术的技术准备水平（TRL）而做出的最新努力，该技术用于未来紧凑、低成本的地球观测系统。新兴的立方体卫星机会允许在3-U立方体卫星上快速开发和空间飞行演示IceCube。由美国宇航局的地球科学技术空间验证（InVEST）计划和科学使命理事会（SMD）资助，IceCube是戈达德太空飞行中心（GSFC）在2.5年内开发和飞行的第一颗立方体卫星，使用商业现货（COTS）组件和子系统。它于2017年5月从国际空间站（ISS）成功释放，获得了15个月的科学数据，并制作了第一张883 GHz云冰的全球地图。它实现了所有使命目标，为今后从立方体卫星星座进行具有成本效益的云观测提供了一条途径。
Cloud ice play important roles in Earth’s climate and weather systems through their interactions with atmospheric radiation, dynamics, energy and precipitation processes. Submillimeter (submm) wave remote sensing at 200-1000 GHz is able to provide the sensitivity not covered by visible (VIS)/infrared (IR) and low-frequency microwave (MW) sensors (10-183 GHz), and measure cloud ice in the middle-to-upper troposphere. The IceCube 883-GHz cloud radiometer is the latest of NASA’s efforts to advance the technology readiness level (TRL) of submm-wave receiver technology for future compact, low-cost implementation of Earth observing systems. Emerging CubeSat opportunities allow a fast-track development and spaceflight demonstration of IceCube on a 3-U CubeSat. Funded by NASA’s In-Space Validation of Earth Science Technologies (InVEST) program and Science Mission Directorate (SMD), IceCube is the first CubeSat developed and flown by Goddard Space Flight Center (GSFC) in 2.5 years, using commercial off-the-shelf (COTS) components and subsystems. It was successfully released from International Space Station (ISS) in May 2017, acquired 15-month science data and produced the first global map of the 883-GHz cloud ice. It achieved all mission objectives and provided a pathway for future cost-effective cloud observations from CubeSat constellation.
