NOAA HRRR - dynamical.org Icechunk Zarr

The High-Resolution Rapid Refresh (HRRR) is a NOAA real-time 3-km resolution, hourly updated, cloud-resolving, convection-allowing atmospheric model, initialized by 3km grids with 3km radar assimilation. Radar data is assimilated in the HRRR every 15 min over a 1-h period adding further detail to that provided by the hourly data assimilation from the 13km radar-enhanced Rapid Refresh.These datasets have been translated to cloud-optimized Icechunk Zarr format by dynamical.org.高分辨率快速刷新（High-Resolution Rapid Refresh，HRRR）是美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）推出的实时3千米分辨率、逐小时更新的云解析、对流允许型大气模式，其初始化基于3千米网格与3千米雷达同化数据。HRRR每15分钟开展一次雷达数据同化，单次同化覆盖1小时时段，相较于13千米雷达增强型快速刷新模式的逐小时数据同化结果，可为其增添更多细节信息。dynamical.org 已将此类数据集转换为云优化型Icechunk Zarr格式。
