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 and unconventional observational data (including satellite and radar data) from the global observation system, this dataset uses the global four-dimensional variational (4D-Var) method and the CMA-GFS global modeling system to provide 3D grid data with a global horizontal resolution of 12.5 km and 40 vertical isobaric layers from the ground upwards, covering forecasts for 0 to 10 days ahead. The dataset includes atmospheric wind field, temperature, humidity, cloud cover, surface precipitation and snowfall, near-surface radiation, near-surface temperature, visibility, radar echo, and other related meteorological elements, which can meet professional service needs in fields such as energy, transportation and agriculture.
