ECMWF ERA5 Reanalysis

ERA5 is the fifth generation of ECMWF atmospheric reanalyses of the global climate, and the first reanalysis produced as an operational service. It utilizes the best available observation data from satellites and in-situ stations, which are assimilated and processed using ECMWF&#39;s Integrated Forecast System (IFS) Cycle 41r2. The dataset provides all essential atmospheric meteorological parameters like, but not limited to, air temperature, pressure and wind at different altitudes, along with surface parameters like rainfall, soil moisture content and sea parameters like sea-surface temperature and wave height. ERA5 provides data at a considerably higher spatial and temporal resolution than its legacy counterpart ERA-Interim. ERA5 consists of high resolution version with 31 km horizontal resolution, and a reduced resolution ensemble version with 10 members. It is currently available since 2008, but will be continuously extended backwards, first until 1979 and then to 1950.

ERA5是欧洲中期天气预报中心（ECMWF）第五代全球气候大气再分析产品，也是首个以业务服务形式产生的再分析产品。该数据集采用了卫星和地面站所能提供的最佳观测数据，这些数据经过ECMWF的集成预报系统（IFS）Cycle 41r2的同化与处理。ERA5提供了所有必要的气象参数，包括但不限于空气温度、气压以及不同高度的风速，以及地表参数如降雨量、土壤湿度含量以及海洋参数如海表温度和波浪高度。与先前的ERA-Interim相比，ERA5的空间和时间分辨率显著提高。ERA5包含31公里水平分辨率的较高分辨率版本，以及包含10个成员的低分辨率集合版本。该数据集自2008年起即可获取，并将持续向前扩展，首先扩展至1979年，最终将回溯至1950年。欲了解更多关于ERA5的信息，请参阅Jon Olauson的论文《ERA5：风力发电建模的新霸主？》
