Enabling collaboration through data and model sharing with CUAHSI HydroShare; CIROH Devcon 25 presentation

Collaboration is central to CIROH. Advancing hydrology research to operations relies on model and data sharing, requiring open data integration, accessible computing, and teamwork. The CUAHSI HydroShare platform was developed to enable researchers to share digital products from their research, including data, models, and workflows, in line with Findable, Accessible, Interoperable, and Reusable (FAIR) principles. This project advances HydroShare for CIROH collaborative research and education with objectives to (1) enhance community data access; (2) establish interoperability with scalable computing; (3) demonstrate computational reproducibility; and (4) establish and grow a CIROH Community on HydroShare. This presentation will show the use of the CIROH 2i2c JupyterHub platform linked to HydroShare for accessing high community value datasets such as NOAA Analysis of Record for Calibration (AORC) Dataset and the hydrofabric dataset of connected rivers, lakes and catchments. The presentation will also cover configuring and running research instances of NextGen subsets to evaluate options for improving the National Water Model as it adopts the NextGen framework.

协作是CIROH的核心宗旨。将水文学研究推进至业务化应用，离不开模型与数据共享，这要求开放数据集成、易用计算与团队协同。CUAHSI HydroShare平台旨在助力研究人员共享其研究产出的各类数字成果，涵盖数据、模型与工作流，其设计遵循可发现、可访问、可互操作、可复用（Findable, Accessible, Interoperable, and Reusable，简称FAIR）原则。本项目针对CIROH的协作研究与教育需求对HydroShare进行升级，具体目标包括：1. 提升社区数据可访问性；2. 实现与可扩展计算的互操作；3. 验证计算可复现性；4. 在HydroShare平台上搭建并壮大CIROH社区。本次报告将演示如何使用与HydroShare对接的CIROH 2i2c JupyterHub平台，获取具有高社区价值的数据集，例如美国国家海洋和大气管理局（NOAA）的校准记录分析（Analysis of Record for Calibration，简称AORC）数据集，以及涵盖连通河流、湖泊与集水区的水文地貌数据集。本次报告还将介绍如何配置并运行NextGen子集的研究实例，以评估在美国国家水模型采用NextGen框架的背景下，可供优化的方案。
