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

| DOI: 10.5065/39C5-Z211

NCEP 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, dew point temperature, wind direction and speed. Data may be available at up to 20 mandatory levels from 1000 millibars to 1 millibar, 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).

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.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
