NCEP ADP Eta (NAM) Subset Surface Observations

NCEP ADP Eta (NAM) Subset Surface Observations are composed of a regional synoptic set of surface data reports centered over North America. These were operationally collected by the National Centers for Environmental Prediction (NCEP). The data includes land and marine reports received via the Global Telecommunications System (GTS). Variables recorded in the reports include pressure, temperature, dew point depression, wind direction and speed. Report time intervals range from hourly to 3-hourly. Precipitation data has been decoded for the U.S. and Canada. DS461.0 [https://rda.ucar.edu/datasets/ds461.0/] provides global surface data coverage.国家环境预测中心（NCEP）ADP Eta（NAM）子集地表观测数据由以北美为中心的区域性天气图地表数据报告组成。这些数据系由国家环境预测中心（NCEP）在运行中收集所得。数据内容涵盖通过全球电信系统（GTS）接收的陆地与海洋报告，其中记录的变量包括气压、气温、露点降低、风向风速等。报告的时间间隔从每小时至每三小时不等。针对美国和加拿大，降水数据已进行解码。DS461.0 [https://rda.ucar.edu/datasets/ds461.0/] 提供了全球地表数据的覆盖范围。
