资源简介：
A zarr-formatted dataset of 1836 reforecast cases (approx. 5 years) from The Weather Company GRAF (Global high-Resolution Atmospheric Forecasting) model, a version of the National Center for Atmospheric Research (NCAR) Model for Predictions Across Scales (MPAS). GRAF is global, but the configuration for this reforecast had a mesh refinement to approx. 4 km over the US, Caribbean Basin, and Europe, and 15 km elsewhere. This model was designed to run much of its computation on graphical processing units, with this development assisted by NVIDIA. The 1836 cases (approx. 5 years) were generated fr...
本数据集采用zarr（Zarr）格式存储，包含1836个再预报个例，总时长约5年，数据源自天气公司（The Weather Company）的GRAF（全球高分辨率大气预报，Global high-Resolution Atmospheric Forecasting）模型，该模型是美国国家大气研究中心（National Center for Atmospheric Research, NCAR）跨尺度预测模型（Model for Predictions Across Scales, MPAS）的衍生版本。
GRAF模型本身覆盖全球范围，但本次再预报所采用的配置，对美国、加勒比海盆地及欧洲区域实施了约4公里的网格加密，其余区域的网格分辨率则为15公里。
该模型的核心计算大量依托图形处理器（Graphics Processing Unit, GPU）完成，其开发过程得到了英伟达（NVIDIA）的技术支持。
