ERA5 Reanalysis

ERA5是第五代ECMWF全球气候和天气再分析资料，提供从1940年至今的逐小时大气、海洋波和陆面数据。该数据库通过数据同化方法将数值模式数据与全球观测数据结合，形成完整一致的全球数据集。ERA5每日更新，延迟约5天，提供0.25°×0.25°水平分辨率的再分析数据和不确定性估计。ERA5 is the fifth-generation ECMWF global climate and weather reanalysis dataset, providing hourly atmospheric, ocean wave, and land surface data from 1940 to the present. This database combines numerical model data with global observational data through data assimilation methods to create a complete and consistent global dataset. ERA5 is updated daily with an approximate 5-day latency, and offers reanalysis data and uncertainty estimates at a horizontal resolution of 0.25°×0.25°.
