ECMWF AIFS ENS - dynamical.org Icechunk Zarr

The Artificial Intelligence Forecasting System (AIFS) is a data driven forecast model developed by the European Centre for Medium-Range Weather Forecasts (ECMWF). AIFS-ENS is the ensemble configuration of AIFS, containing 51 ensemble members. AIFS is trained on ECMWF's ERA5 re-analysis and ECMWF's operational numerical weather prediction (NWP) analyses.These datasets have been translated to cloud-optimized Icechunk Zarr format by dynamical.org.人工智能预报系统（Artificial Intelligence Forecasting System，AIFS）是由欧洲中期天气预报中心（European Centre for Medium-Range Weather Forecasts，ECMWF）开发的数据驱动型预报模型。AIFS-ENS为AIFS的集合预报配置版本，包含51个集合成员。AIFS以ECMWF的ERA5再分析资料以及ECMWF的业务数值天气预报（Numerical Weather Prediction，NWP）分析场作为训练数据。上述数据集已由dynamical.org转换为适配云环境的Icechunk Zarr格式。
