全球数值天气预报产品

基于全球观测系统的全天候的常规和卫星、雷达等非常规观测资料，采用全球四维变分方法和CMA-GFS全球模式系统，提供未来0-10天全球水平分辨率12.5km, 地面垂直向上40个等压面层的三维网格数据，涵盖大气风场、温度、湿度、云量，地表雨雪量、近地面辐射量、温度、能见度、雷达回波等，满足能源、交通和农业等专业服务。Based on all-weather conventional observation data and unconventional observations including satellite and radar data sourced from the global observation system, this dataset adopts the global 4-dimensional variational (4D-Var) method and the CMA-GFS global modeling system to generate 3D grid data with a global horizontal resolution of 12.5 km and 40 vertical isobaric layers from the ground upward for the 0–10 day forecast period. The dataset covers various parameters including atmospheric wind fields, temperature, humidity, cloud cover, surface precipitation (rain and snow) amount, near-surface radiation flux, near-surface air temperature, visibility, radar echoes, and more, meeting professional service requirements for industries such as energy, transportation, and agriculture.
