NCEP ADP Eta (NAM) Subset Surface Observations, October 2000 - October 2010

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.
