NCEP ADP Global Upper Air Observational Weather Data, October 1999 - continuing

NCEP Automated Data Processing (ADP) Global Upper Air Observational Weather Data are composed of global upper air weather reports operationally collected by the National Centers for Environmental Prediction (NCEP). These include radiosondes, pibals and aircraft reports from the Global Telecommunications System (GTS), and satellite data from the National Environmental Satellite Data and Information Service (NESDIS). The reports can include pressure, geopotential height, air temperature, dewpoint temperature, wind direction and speed. Data may be available at up to 20 mandatory levels from 1000mb to 1mb, plus a few significant levels. Report intervals range from hourly to 12 hourly. These data are the primary input to the NCEP Global Data Assimilation System (GDAS), which is used to create the NCEP Final Tropospheric Analyses (FNL). NCAR's Data Services Section (DSS) maintains this dataset. Please see the external link to access the data.

美国国家环境预报中心（National Centers for Environmental Prediction, NCEP）自动化数据处理（Automated Data Processing, ADP）全球高空观测气象数据集，由该中心业务化采集的全球高空气象报告构成。此类报告涵盖源自全球电信系统（Global Telecommunications System, GTS）的无线电探空仪、测风气球及航空器观测报告，以及来自国家环境卫星数据和信息服务局（National Environmental Satellite Data and Information Service, NESDIS）的卫星观测数据。观测报告可包含气压、位势高度、气温、露点温度、风向及风速等要素。数据可覆盖从1000毫巴至1毫巴的最多20层标准等压面层，外加若干显著层次。观测报告的时间间隔为每小时至每12小时不等。该数据集是美国国家环境预报中心全球数据同化系统（Global Data Assimilation System, GDAS）的主要输入数据，后者用于生成美国国家环境预报中心对流层最终分析场（Final Tropospheric Analyses, FNL）。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）负责维护该数据集。请通过外部链接获取该数据集。
