EPA Dynamically Downscaled Ensemble (EDDE)

The data are a subset of the EPA Dynamically Downscaled Ensemble (EDDE), Version 1. EDDE is a collection of physics-based modeled data that represent 3D atmospheric conditions for historical and future periods under different scenarios. The EDDE Version 1 datasets cover the contiguous United States at a horizontal grid spacing of 36 kilometers at hourly increments. EDDE Version 1 includes simulations that have been dynamically downscaled from multiple global climate models (GCMs) under both mid- and high-emission scenarios from the Fifth Coupled Model Intercomparison Project (CMIP5) using the Weather Research and Forecasting (WRF) model. Scenarios were downscaled from the Community Earth System Model (CESM) and the Geophysical Fluid Dynamics Laboratory (GFDL) Coupled Model version 3 (CM3). Simulations followed the historical periods 1975-2005 (CESM only) and 1995-2005 (both CESM and CM3), and Representative Concentration Pathways (RCP) 4.5 for 2025-2100 (CESM only), RCP6.0 for 2025-2055 (CESM only), and RCP8.5 (both CESM and CM3). Data are in Network Common Data Form (netCDF) version 4, which is used in atmospheric modeling. The EDDE data in netCDF are further written to adhere to principles of Climate and Forecasting System (CF) Compliance to enhance portability and interoperability with data from other sources. The files are self-describing with metadata included in the netCDF header.

本数据集为美国环境保护署动态降尺度集合（EDDE）的子集，版本一。EDDE汇聚了一系列基于物理模型构建的数据，旨在表征历史时期及不同情景下未来时期的3D大气条件。EDDE版本一数据集覆盖了美国本土，水平网格间距为36公里，以小时为时间间隔进行数据采集。该版本的数据集包含从多个全球气候模型（GCMs）动态降尺度得到的模拟结果，这些模型涵盖了第五次耦合模式比较计划（CMIP5）下的中高排放情景。降尺度过程采用了天气研究预报（WRF）模型，并将情景数据从社区地球系统模型（CESM）和地球物理流体动力学实验室耦合模型版本3（CM3）中进行提取。模拟结果的历史时期涵盖了1975-2005年（仅CESM）和1995-2005年（CESM与CM3），以及代表浓度路径（RCP）4.5下的2025-2100年（仅CESM）、RCP6.0下的2025-2055年（仅CESM）和RCP8.5下的2025-2055年（CESM与CM3）。数据格式为网络通用数据格式（netCDF）版本4，适用于大气模式建模。netCDF格式的EDDE数据进一步遵循气候与预报系统（CF）一致性原则，以增强数据便携性和与其他来源数据的互操作性。文件包含自描述性元数据，位于netCDF头信息中。数据参考：[https://doi.org/10.23719/1530964](https://doi.org/10.23719/1530964)。以下为一些描述EDDE的同行评审出版物（不包括名称“EDDE”）：[https://doi.org/10.1080/10962247.2021.1970048](https://doi.org/10.1080/10962247.2021.1970048)、[https://doi.org/10.5194/acp-18-15471-2018](https://doi.org/10.5194/acp-18-15471-2018)、[https://doi.org/10.1080/10962247.2014.996270](https://doi.org/10.1080/10962247.2014.996270)、[https://doi.org/10.1175/JCLI-D-15-0233.1](https://doi.org/10.1175/JCLI-D-15-0233.1)、[https://doi.org/10.1002/2014JD021785](https://doi.org/10.1002/2014JD021785)。
