Climate Change Knowledge Portal: Observed Climate Data, ERA5 0.25-degree

The Climate Change Knowledge Portal (CCKP) is the World Bank's designated climate data service. CCKP offers a comprehensive suite of climate data and products that are derived from the latest generation of climate data archives. CCKP implements a systematic way of pre-processing the raw observed and model-based projection data to enable inter-comparable use across a broad range of applications. Data is available across an expansive range of climate variables and can be extracted per individual spatial units, variables, select timeframes, climate projection scenarios, across ensembles or individual models. Data is available as global gridded or spatially aggregated to national, subnational, watershed, and Exclusive Economic Zone scaled.The Observed Climate Data, ERA5 0.25-degree dataset, ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1950 to 2022. ERA5 is a satellite derived dataset, originally produced by the Copernicus Climate Change Service (C3S) at ECMWF at on original grid of 0.50-degree. ERA5 products derived by CCKP are downscaled and available at 0.25-degree, from 1950-2022.Global gridded NetCDF files can be accessed via https://registry.opendata.aws/wbg-cckp/Pre-computed statistics for spatially aggregated data is available as API or xls via https://climateknowledgeportal.worldbank.org/download-data

气候变化知识门户（Climate Change Knowledge Portal，简称CCKP）是世界银行指定的官方气候数据服务平台。CCKP提供一套由最新一代气候数据档案衍生而来的全面气候数据与产品集。CCKP采用系统化流程对原始观测数据及基于模型的投影数据进行预处理，以支持其在各类应用场景中实现跨场景对比使用。该数据集涵盖丰富多样的气候变量，支持按单个空间单元、变量、选定时间范围、气候投影情景，以及集合模拟或单个模型进行数据提取。数据可采用全球格网形式发布，或经空间聚合为国家、次国家、流域及专属经济区（Exclusive Economic Zone）尺度的数据集。观测气候数据方面，ERA5 0.25度格网数据集：ERA5是欧洲中期天气预报中心（European Centre for Medium-Range Weather Forecasts，ECMWF）推出的第五代全球大气再分析数据集，时间覆盖范围为1950年1月至2022年。该数据集为卫星衍生数据，最初由欧洲中期天气预报中心下属的哥白尼气候变化服务（Copernicus Climate Change Service，C3S）以0.50度原始格网分辨率制作完成。CCKP衍生的ERA5产品已进行降尺度处理，分辨率为0.25度，时间范围为1950年至2022年。全球格网NetCDF格式文件可通过https://registry.opendata.aws/wbg-cckp/获取。空间聚合数据的预计算统计值可通过API或XLS格式获取，访问地址为https://climateknowledgeportal.worldbank.org/download-data
