NCEP FNL Operational Model Global Tropospheric Analyses, continuing from July 1999

These National Center for Environmental Prediction (NCEP) Final Analysis (FNL) Operational Global Analysis data are on 1.0x1.0 degree grids continuously at every six hours. This product is from the Global Forecast System (GFS) that is operationally run four times a day in near-real time at NCEP. The analyses are available on the surface, at 26 mandatory (and other pressure) levels from 1000mb to 10mb, in the surface boundary layer and at some sigma layers, the tropopause and a few others. Parameters include surface pressure, sea level pressure, geopotential height, temperature, sea surface temperature, soil values, ice cover, relative humidity, u- and v- winds, vertical motion, vorticity and ozone. The archive time series is continuously extended to a near-current date. It is not maintained in real-time. This dataset is maintained by the National Center for Atmospheric Research's (NCAR) Data Services Section (DSS). Please see the external link to access the data.

本数据集为美国国家环境预报中心（National Center for Environmental Prediction, NCEP）最终分析（Final Analysis, FNL）业务化全球分析数据，空间分辨率为1.0°×1.0°，时间序列为每6小时更新一次的连续序列。该数据集依托美国国家环境预报中心每日以近实时模式运行四次的全球预报系统（Global Forecast System, GFS）生成。该分析数据覆盖多个垂直层次：地面、1000百帕（mb）至10百帕的26个标准等压面（及其他气压层）、地面边界层、部分σ坐标层、对流层顶及其他少量层次。涵盖的参数包括地面气压、海平面气压、位势高度、气温、海表温度、土壤参数、冰盖覆盖率、相对湿度、纬向风（u风）与经向风（v风）、垂直运动、涡度及臭氧。其存档时间序列会持续更新至接近当前的日期，但并未采用实时维护模式。本数据集由美国国家大气研究中心（National Center for Atmospheric Research, NCAR）数据服务部（Data Services Section, DSS）负责维护。请通过外部链接获取该数据集。
