NCEP ADP Global Surface Observational Weather Data, October 1999 - continuing

NCEP ADP Global Surface Observational Weather Data are composed of surface weather reports operationally collected by the National Centers for Environmental Prediction (NCEP). The data includes land and marine surface reports received via the Global Telecommunications System (GTS). Variables recorded in the reports include pressure, air temperature, dew point temperature, wind direction and speed. Precipitation data has been decoded for the U.S. and Canada. Report intervals range from hourly to 3 hourly. These data are the primary input to the NCEP Global Data Assimilation System (GDAS).

Full daily data can be downloaded in BUFR or LITTLE_R format. Spatial subsets decoded into ASCII can also be selected by latitude/longitude or station ID.
