Met Office Blended Probabilistic Forecast – Global gridded percentiles

This product provides percentile weather forecasts. The grid resolution is approximately 20km and covers the whole globe. It is produced by the Met Office IMPROVER Blended Probabilistic Forecast system. It is available in NetCDF format. Blended Probabilistic Forecast data is derived from the Met Office's operational NWP (Numerical Weather Prediction) ensembles and nowcasts. To give more reliable predictions, these are then blended and calibrated using the IMPROVER pipeline, and verified using spread–skill and reliability checks. This is 1 of 8 Blended Probabilistic Forecast products published by the Met Office on the Registry of Open Data on AWS. Data is available for the Global and UK domains, as gridded and spot (site-specific), and represented as percentiles and probabilities. This info is correct as of April 2026, but some things (like the number of sites, parameters and timesteps) may change in future. How perce...

本产品提供百分位气象预报。其网格分辨率约为20千米，覆盖全球范围。本产品由英国气象局（Met Office）的IMPROVER混合概率预报系统（IMPROVER Blended Probabilistic Forecast system）生成，数据以NetCDF格式提供。混合概率预报数据源自英国气象局的业务数值天气预报（Numerical Weather Prediction，NWP）集合预报与临近预报。为获得更可靠的预报结果，上述数据将通过IMPROVER流程进行融合与校准，并通过离散技能（spread-skill）与可靠性检验进行验证。本产品为英国气象局在AWS开放数据注册表（Registry of Open Data on AWS）上发布的8款混合概率预报产品之一。数据覆盖全球与英国区域，包含格点数据与单点（站点专属）数据，并以百分位与概率形式呈现。本说明截至2026年4月有效，但部分内容（如站点数量、参数与时间步长）未来可能发生变更。本说明后续内容为……
