The project, "CC*DNI Instrument: High Performance Reliable Network Access to MLO Science Instruments", addresses the problem of network limitations at the Mauna Loa Observatory (MLO) located on the island of Hawaii in the Pacific ocean. The site is owned and operated by the National Oceanic and Atmospheric Administration, Earth System Research Laboratory Global Monitoring Division and cooperatively used by the National Center for Atmospheric Research's High Altitude Observatory and the Institute for Astronomy, a research organization of the University of Hawaii (UH). A wide range of important science observation data is produced by the various instruments located at MLO. Among this data is a widely-used, 50+ year continuous record of atmospheric carbon dioxide levels at Mauna Loa. Less well known are data that measure ozone levels in the upper atmosphere, solar activity such as solar flares and coronal mass ejections, young variable stars and mid-size, potentially hazardous asteroids. This data is of national and global significance for policy and public safety and welfare decisions in areas related to measuring and predicting global warming, forecasting disruptions to communications and navigation caused by solar transient events and detecting and predicting Earth impacts of mid-sized asteroids.Improvements to telescopes and instruments cause volumes of science data produced to increase exponentially over time. Commercial grade, licensed-spectrum wireless radio point-to-point network links are used to solve the critical "last mile" problem of connecting the science instruments located at MLO to the robust University of Hawaii (UH) network for transmission to researchers in Hawaii, the United States and across the globe. The MLO network supports a rapidly growing volume of data (1.5TB/day) originating from instruments such as COSMO K- Coronagraph (KCor), Coronal Multi-channel Polarimeter (CoMP), Precision Solar Photometric Telescope (PSPT), Very Young Stellar Objects Survey (VYSOS), Asteroid Terrestrial-Impact Last Alert System (ATLAS) and COSMO Chromospheric Magnetometer (ChroMag). Expected science results made possible by these MLO network improvements include follow up observations of Near Earth Objects, supernovae, gamma ray bursts, and young variable stars; solar observations in real time for space weather forecasts and real-time atmospheric monitoring. The broader impact of the science enabled is to build and support global awareness of environmental and astronomy research, to enable collaborative research with global partners and support the dissemination of unique data sets of immense value to research communities, policy and decision makers and the lay public.

该项目“CC*DNI仪器：MLO科学仪器的高性能可靠网络接入”解决了位于太平洋夏威夷岛上的莫纳罗亚天文台（MLO）的网络限制问题。该站点由国家海洋和大气管理局地球系统研究实验室全球监测司拥有和运营，并由国家大气研究中心的高海拔观测站和天文学研究所（夏威夷大学的一个研究组织）合作使用。位于MLO的各种仪器产生了广泛的重要科学观测数据。在这些数据中，有一个被广泛使用的，在莫纳罗亚山连续50多年的大气二氧化碳水平记录。不太为人所知的是测量高层大气中臭氧水平、太阳活动（如太阳耀斑和日冕物质抛射）、年轻变星和中等大小、具有潜在危险的小行星的数据。这些数据对于测量和预测全球变暖、预测太阳瞬变事件对通信和导航造成的干扰以及检测和预测中型小行星对地球的影响等相关领域的政策、公共安全和福利决策具有国家和全球意义。望远镜和仪器的改进导致产生的科学数据量随着时间的推移呈指数级增长。商用级许可频谱无线电点对点网络链路用于解决将位于MLO的科学仪器连接到强大的夏威夷大学（UH）网络的关键“最后一英里”问题，以便传输给夏威夷、美国和地球仪各地的研究人员。MLO网络支持来自COSMO K-日冕仪（KCor）、日冕多通道偏振仪（CoMP）、精密太阳光度望远镜（PSPT）、非常年轻恒星天体巡天（VYSOS）、小行星陆地撞击最后警报系统（ATLAS）和COSMO色球磁力仪（ChroMag）等仪器的快速增长的数据量（1.5TB/天）。通过这些MLO网络的改进而可能取得的预期科学成果包括对近地天体、超新星、伽马射线爆发和年轻变星的后续观测;用于空间天气预报和实时大气监测的真实的太阳观测。科学的更广泛影响是建立和支持全球对环境和天文学研究的认识，使与全球合作伙伴的合作研究成为可能，并支持向研究界、政策制定者和决策者以及普通公众传播具有巨大价值的独特数据集。
