A three-day workshop will be held at the University of Colorado-Boulder in Spring 2014 involving 25 early-career Earth scientists with a focus on the potentials for utilizing the next generation of Light Detection and Ranging (LiDAR) analysis techniques to answer research questions across the transdisciplinary boundaries of Critical Zone (CZ) science: hydrology, ecology, geomorphology, and geology. LiDAR technology is capable of resolving vegetation, terrain, and snowpack data at extremely high resolutions using ground-based (terrestrial) and aircraft-mounted laser ranging equipment. The growth of LiDAR data collection has outpaced the potential for CZ scientists to learn about new analysis techniques needed for research applications, which has left the CZ community 'data-rich' but 'information-poor' regarding LiDAR data. The workshop is therefore an important opportunity for early-career scientists to meet and learn about transformative LiDAR analysis tools and better utilize the LiDAR datasets already collected by the National Science Foundation's Critical Zone Observatory (CZO) network and similar CZ field sites from around the world. The workshop has three clear objectives: 1. Inform early-career CZ scientists on cutting-edge LiDAR analysis techniques, 2. Identify opportunities to apply LiDAR analysis techniques across the disciplinary boundaries of CZ science, and 3. Develop a five-year vision for advancing CZ science with new LiDAR data products that is articulated in a discussion paper. For one day of the workshop the instructors will rotate between three topical groups: 1. Watershed hydrology, 2. Forest ecology and management, and 3. Geomorphic landforms and lithology. The second half of the workshop will be spent synthesizing these ideas into a vision for advancing CZ science using transdisciplinary LiDAR analysis techniques to be published in a top-level peer-reviewed Earth science journal. The workshop offers a unique opportunity to develop collaborations among multidisciplinary early-career CZ scientists working with LiDAR data from around the world and engage the wider CZ community using course materials and journal publications.

2014 年春季，科罗拉多大学博尔德分校将举办为期三天的研讨会，由 25 名职业生涯早期的地球科学家参加，重点讨论利用下一代光探测和测距 (LiDAR) 分析技术来回答关键区域 (CZ) 科学跨学科边界的研究问题：水文学、生态学、地貌学和地质学。激光雷达技术能够使用陆基（地面）和机载激光测距设备以极高分辨率解析植被、地形和积雪数据。 LiDAR 数据收集的增长超出了 CZ 科学家了解研究应用所需的新分析技术的潜力，这使得 CZ 社区在 LiDAR 数据方面“数据丰富”，但“信息匮乏”。因此，对于处于职业生涯早期的科学家来说，该研讨会是一个重要的机会，可以认识和了解变革性 LiDAR 分析工具，并更好地利用美国国家科学基金会关键区域天文台 (CZO) 网络和世界各地类似 CZ 现场站点已经收集的 LiDAR 数据集。该研讨会有三个明确的目标：1. 向处于职业生涯早期的 CZ 科学家介绍尖端 LiDAR 分析技术，2. 寻找跨 CZ 科学学科边界应用 LiDAR 分析技术的机会，以及 3. 制定一个五年愿景，通过讨论论文中阐述的新 LiDAR 数据产品推进 CZ 科学。在一天的研讨会中，讲师将在三个主题组之间轮流讲授：1. 流域水文学，2. 森林生态和管理，以及 3. 地貌地貌和岩性。研讨会的后半部分将利用跨学科 LiDAR 分析技术将这些想法综合为推进 CZ 科学的愿景，并在顶级同行评审的地球科学期刊上发表。该研讨会提供了一个独特的机会，让多学科早期职业 CZ 科学家利用来自世界各地的 LiDAR 数据开展合作，并利用课程材料和期刊出版物吸引更广泛的 CZ 社区。
