Abstract. This article introduces the 2023 National Offshore Wind data set (NOW-23), which offers the latest wind resource information for offshore regions in the United States. NOW-23 supersedes, for its offshore component, the Wind Integration National Dataset (WIND) Toolkit, which was published a decade ago and is currently a primary resource for wind resource assessments and grid integration studies in the contiguous United States. By incorporating advancements in the Weather Research and Forecasting (WRF) model, NOW-23 delivers an updated and cutting-edge product to stakeholders. In this article, we present the new data set which underwent regional tuning and performance validation against available observations and has data available from 2000 through, depending on the region, 2019–2022. We also provide a summary of the uncertainty quantification in NOW-23, along with NOW-WAKES, a 1-year post-construction data set that quantifies expected offshore wake effects in the US Mid-Atlantic lease areas. Stakeholders can access the NOW-23 data set at https://doi.org/10.25984/1821404 (Bodini et al., 2020).

2023 年国家海上风电数据集 (NOW-23)

摘要。本文介绍了2023年国家海上风电数据集（NOW-23），该数据集提供了美国近海地区的最新风资源信息。 NOW-23 取代了其海上组件风电集成国家数据集 (WIND) 工具包，该工具包于十年前发布，目前是美国本土风资源评估和电网集成研究的主要资源。通过整合天气研究和预报 (WRF) 模型的进步，NOW-23 为利益相关者提供了更新的尖端产品。在本文中，我们介绍了新的数据集，该数据集根据可用观测值进行了区域调整和性能验证，并提供了从 2000 年到 2019 年至 2022 年（具体取决于区域）的数据。我们还提供了 NOW-23 中不确定性量化的摘要，以及 NOW-WAKES，这是一个施工后 1 年的数据集，用于量化美国中大西洋租赁区的预期离岸尾流效应。利益相关者可以通过 https://doi.org/10.25984/1821404 访问 NOW-23 数据集（Bodini 等人，2020）。
