NCEP FNL Operational Model Global Surface Analyses

These NCEP FNL (Final) Operational Global Analysis data are on pairs of 2.5 by 2.5 degree hemispheric grids every twelve hours. This product was from the Global Forecast System (GFS) that was run operationally in near-real time at NCEP. DSS prepared this surface subset from ds082.0.The analyses are available on the surface, at 1000mb and a boundary layer. Parameters include surface pressure, sea level pressure, geopotential height, temperature, sea surface temperature, soil temperature, water content of soil, ice cover, water equivalent of snow depth, relative humidity, specific humidity, u- and v-wind components, minimum temperature, maximum temperature and land-sea mask.More information is available [http://rda.ucar.edu/datasets/ds083.1/more.html]本数据集为美国国家环境预报中心（National Centers for Environmental Prediction, NCEP）FNL（最终）业务全球分析数据，以每12小时更新一次的2.5°×2.5°半球网格对格式存储。该数据产品源自美国国家环境预报中心以近实时方式业务运行的全球预报系统（Global Forecast System, GFS）。本地表子集由数据支持服务（DSS）从ds082.0数据集提取生成。分析数据覆盖地表、1000百帕（1000mb）以及边界层三个层级，涵盖的参数包括地表气压、海平面气压、位势高度、气温、海表温度、土壤温度、土壤含水量、冰覆盖范围、雪深水当量、相对湿度、比湿、u风分量与v风分量、最低气温、最高气温以及海陆掩码。更多详细信息可访问：[http://rda.ucar.edu/datasets/ds083.1/more.html]
