Abstract

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.

description: The NSF NCAR Geoscience Data Exchange - Integrated Research Data Commons (GDEX) contains an extensive collection of meteorological, atmospheric composition, and oceanographic observations and model outputs to support Earth System Science research. GDEX supports "data proximate" computational research through its integration with NSF NCAR High Performance Compute services [https://arc.ucar.edu/resources], which are made accessible to US researchers through a range of allocations opportunities [https://arc.ucar.edu/xras_submit/opportunities].
