Gridded dataset underpinning the Copernicus Interactive Climate Atlas

This catalogue entry provides the gridded climate data (monthly/annual timeseries) used for the Copernicus Climate Change Service Atlas (C3S Atlas). The datasets consists of observations (E-OBS), reanalyses (ERA5, ERA5-Land and ORAS5) and global (CMIP5 and CMIP6) and regional (CORDEX) climate projections for the variables and indices included in the C3S Atlas. This dataset complements the Gridded monthly climate projection dataset underpinning the IPCC AR6 Interactive Atlas (IPCC Atlas dataset hereafter), including new datasets, variables and indices. All data sources included in this entry are available in the Climate Data Store (CDS). Contrary to the frozen IPCC Atlas dataset, this entry will have an evolution adding new data on a regular basis describing various types of climatic impact characteristics: heat and cold, wet and dry, snow and ice, wind and radiation, ocean, and circulation characteristics of the climate system.
This dataset includes gridded information with monthly/annual temporal resolution for observations/reanalyses of the recent past and climate projections for the 30 variables and indices computed from daily/monthly data across the different datasets. The climate projections are based on Representative Concentration Pathways (RCP) / Shared Socioeconomic Pathways (SSP) scenarios. The ensemble (and some single-model) datasets are harmonised using regular latitude-longitude grids with horizontal resolutions of 2° (CMIP5), 1° (CMIP6), 0.5° (ORAS5), 0.25° (CORDEX-CORE and ERA5), 0.125º (CORDEX-EUR-11, E-OBS) and 0.1º (ERA5-Land).
This dataset allows the reproduction, expansion and customisation of the climate change products provided interactively by the Copernicus Interactive Climate Atlas. This is an interactive web application displaying global/regional maps of observed trends and climate changes for future periods across scenarios or for global warming levels, and regionally-aggregated time series, seasonal cycle plots and climate stripes.
Related datasets, also available through the CDS, include E-OBS, ERA5, ERA5-Land, ORAS5, CMIP5/6 and CORDEX. Links to these datasets can be found in the sidebar under "Related data".

本目录条目提供了用于哥白尼气候变化服务图集（C3S 图集）的格网化气候数据（月度/年度时间序列）。该数据集包括观测数据（E-OBS）、再分析数据（ERA5、ERA5-Land 和 ORAS5）以及全球（CMIP5 和 CMIP6）和区域（CORDEX）气候预测，涉及 C3S 图集包含的变量和指数。本数据集补充了支撑 IPCC AR6 互动图集（IPCC 图集数据集）的格网化月度气候预测数据集，包括新的数据集、变量和指数。本条目中包含的所有数据源均可在气候数据存储库（CDS）中获取。与固定的 IPCC 图集数据集不同，本条目将不断演变，定期添加新的数据，描述各种气候影响特征：热与冷、湿与干、雪与冰、风与辐射、海洋以及气候系统的环流特性。

本数据集包括具有月度/年度时间分辨率的格网化信息，用于近期过去的观测/再分析以及从不同数据集中的每日/月度数据计算出的 30 个变量和指数的气候预测。气候预测基于代表性浓度路径（RCP）/共享社会经济路径（SSP）情景。集合（以及一些单模型）数据集使用规则的经纬度网格进行调和，水平分辨率为 2°（CMIP5）、1°（CMIP6）、0.5°（ORAS5）、0.25°（CORDEX-CORE 和 ERA5）、0.125º（CORDEX-EUR-11、E-OBS）和 0.1º（ERA5-Land）。

本数据集允许复制、扩展和定制哥白尼互动气候图集提供的气候变化产品。这是一个交互式网络应用程序，展示未来时期在不同情景或全球变暖水平下的观测趋势和气候变化的全局/区域地图，以及区域汇总的时间序列、季节周期图和气候条纹。

通过 CDS 可获取的相关数据集包括 E-OBS、ERA5、ERA5-Land、ORAS5、CMIP5/6 和 CORDEX。这些数据集的链接可在侧边栏的“相关数据”下找到。
