This collection of surface and upper air observations were made during the GARP Atlantic Tropical Experiment (GATE). GATE was the first major experiment of the Global Atmospheric Research Program.
This dataset contains observations from U.S. and some foreign aircraft during the GARP Atlantic Tropical Experiment (GATE). The GATE period was from June to September 1974.
This dataset contains flight-level aircraft data collected during the GARP Atlantic Tropical Experiment (GATE) from commercial and research aircraft. The GATE period was from June to September 1974.
This dataset contains daily precipitation data for 1974 for stations in several African countries. These data were provided by ASECNA (Agency for Air Traffic Safety in Africa and Madagascar) as part of the GATE experiment.
This data set contains the polar digital tilt sequence data (normally one sequence each 15 minutes consisting of a base tilt scan followed by scans taken at successively higher tilt angles) collected with the 2 NOAA C-band radars for the 3 phases of GATE. Each scan contains equivalent reflectivity factors for 2-degree by 2km data bins out to a maximum range of 260 km. The intensity resolution is 1 dBZ. The raw digital values for the polar data bins were obtained in real time by using a Digital Video Integrator and Processor (DVIP).
The C-band radar aboard the Canadian ship C.C.G.S. Quadra collected reflectivity data at 1 degree by 1 km resolution at various antenna tilt angles. A single 360-degree scan at a fixed tilt angle took approximately 20 seconds to complete. A Digital Video Integrator and Processor (DVIP) converted the analog reflectivities to 8-bit digital values. The center of the first gate was 10.5 km from the radar, with equivalent reflectivities recorded for 200 gates in the radial direction.
NCAR received the binary-format Quadra radar data on half-inch magnetic tapes from the Radar Weather Observatory at McGill University in April 1977. The raw reflectivity data were converted to netCDF format in 2024, and additionally, netCDF files containing full scans (sweeps) at each tilt angle are planned for later 2024, with equivalent reflectivity values converted to dBZ.
This dataset contains uncorrected teletype data that were collected during the GARP Atlantic Tropical Experiment in 1974.
This dataset contains 100 days of tropical wind analyses for the 300mb, 250mb, and 200mb levels. These analyses were provided by T.N. Krishnamurti at Florida State University. The u- and v-components of the wind are contained in a 2.5-degree grid covering the tropical globe.
This Global Atmospheric Research Programme (GARP) dataset was compiled from observations received operationally at the National Meteorological Center (NMC) and the Environmental Technical Applications Center (ETAC), from teletype-punched cards, and from special mailed in reports. Data for June 1970 include global upper air and surface observations from land stations, global surface marine data, and global aircraft reports.
This satellite dataset was prepared for the period covering the GARP Atlantic Tropical Experiment (GATE) in 1974. The raw data are from the first Synchronous Meteorological Satellite (SMS-1), which provided a good distortion-free view of the GATE ship array.
These volumes contain the Ooyama, Esbensen and Chu analysis of upper air soundings taken during Phase III of GATE. The analyzed data has been interpolated to a regular grid using a statistical interpolation technique developed by Ooyama (1987). The method was applied to the wind data by KV Ooyama and J-H Chu, and to the temperature and relative humidity data by SK Esbensen. A technical report on the temperature and relative humidity analysis is available from SK Esbensen .
The US National Center for Atmospheric Research partnered with the IBS Center for Climate Physics in South Korea to generate the CESM2 Large Ensemble which consists of 100 ensemble members at 1 degree spatial resolution covering the period 1850-2100 under CMIP6 historical and SSP370 future radiative forcing scenarios. Data sets from this ensemble were made downloadable via the Climate Data Gateway on June 14, 2021. NCAR has copied a subset (currently ~500 TB) of CESM2 LENS data to Amazon S3 as part of the AWS Public Datasets Program. To optimize for large-scale analytics we have represented the data as ~275 Zarr stores format accessible through the Python Xarray library. Each Zarr store contains a single physical variable for a given model run type and temporal frequency (monthly, daily).
The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) is a global ocean marine meteorological and surface ocean dataset. It is formed by merging many national and international data sources that contain measurements and visual observations from ships (merchant, navy, research), moored and drifting buoys, coastal stations, and other marine and near-surface ocean platforms. Each marine report contains individual observations of meteorological and oceanographic variables, such as sea surface and air temperatures, wind, pressure, humidity, and cloudiness. The coverage is global and sampling density varies depending on date and geographic position relative to shipping routes and ocean observing systems.
The latest Release 3.0 (R3.0) of ICOADS covers 1662-2014, and is coupled with improved "preliminary" monthly data and product extensions past 2014. R3.0 includes changes designed to enable more effective exchange of information describing data quality between ICOADS, reanalysis centers, data set developers, scientists and the public. These user-driven innovations include the assignment of a unique identifier (UID) to each marine report, to enable tracing of observations, linking with reports and improved data sharing. Other revisions and extensions of the International Maritime Meteorological Archive (IMMA) common data format incorporate new near-surface oceanographic data elements and cloud parameters. Many new input data and metadata sources have been assembled, and updates and improvements to existing data sources, or removal of erroneous data, made.

The coverage is global and sampling density varies depending on date and geographic position relative to shipping routes and ocean observing systems. The monthly summary time series are available at 2-degree (since 1800) and 1-degree (since 1960) spatial resolutions. Observations (22 observed and computed parameters) taken in each month for a give spatial latitude by longitude box are statistically summarized (e.g. mean, median, number of observations, etc) and NOT interpolated or analyzed to fill data voids.
The following datasets are recommended for ancillary use only and not as primary research datasets. They have likely been superseded by newer and better datasets.
