NASA's TEMPO satellite provides high-resolution atmospheric data over North America, with a native spatial resolution of ~10 km². The dataset includes Level 1 radiance and irradiance measurements, Level 2 trace gas and ozone retrievals at native resolution, and Level 3 gridded products for nitrogen dioxide, formaldehyde, ozone, and cloud properties. All described data products reached a provisional validation status on December 9, 2024.
Global satellite observations of tropospheric formaldehyde (HCHO) total column density are provided by the Copernicus Sentinel-5 Precursor (S5P) mission's TROPOMI instrument. The dataset, processed using the Differential Optical Absorption Spectroscopy (DOAS) method, offers high spatial resolution measurements of approximately 5.5 km at nadir. It is part of a suite of atmospheric composition products designed for monitoring air quality and pollution sources.
A deep crustal seismic data acquisition project proposed for the offshore Otway Basin in southeastern Australia. The survey, designated AGSO Survey 137, aimed to collect up to approximately 4000 km of data between early December 1994 and late January 1995. The project was conducted by the Australian Ocean Data Network to study the basin's architecture and extensional processes.
Rainfall distribution statistics provide gridded estimates for the African continent and Madagascar based on NASA's Tropical Rainfall Measuring Mission (TRMM) data. The dataset contains 14-year mean monthly values for total amount, frequency, intensity, and duration, plus Markov chain and gamma-distribution parameters for temporal downscaling. Data is presented in 12 netCDF files with a 0.25-degree spatial resolution.
NASA collected visible-near infrared spectral reflectance and ancillary environmental measurements along a 100-meter transect near Utqiagvik, Alaska. Weekly reflectance data captures the growing seasons from 2000 to 2002, with a single additional measurement in 2022. The dataset includes vegetation cover, surface temperature, permafrost depth, and soil temperature.
A magnitude 7.9 earthquake on 20 July 1975 caused at least $300,000 (Australian) in damage in the southern Bougainville region. The event, documented by the Australian Ocean Data Network, triggered a two-metre tsunami, landslides, liquefaction, and damage to villages and mining infrastructure. Aftershocks occurred in a roughly elliptical area of 12,500 square kilometres off the southwestern coast of Bougainville.
1999 to 2016 global monthly methane emissions estimates are provided at 1-degree spatial resolution, disaggregated into fossil fuel, microbial, and pyrogenic sources. The data was generated by NASA using the TM5-4DVAR inversion system, assimilating atmospheric CH4 and d13CH4 measurements. It offers a detailed 18-year record for analyzing anthropogenic and natural methane source contributions.
February-April 1995 cruise report from the R.V. Aurora Australis detailing a marine geoscience program in Prydz Bay and the Kerguelen Plateau. The report, from the Australian Ocean Data Network, outlines aims to study modern sedimentary processes and Plio-Pleistocene environmental history to understand Antarctic ice sheet and Southern Ocean circulation changes. Goals include providing palaeoenvironmental statements for time intervals from 0-10,000 years up to 0-5,000,000 years.
A 2019 series of gravity grids for Australia, combining over 1.4 million ground observations from the 1940s onward with satellite and airborne data. The grids, produced by Geoscience Australia and GNS Science, feature a 400-metre cell size and include Free Air Anomaly, Complete Bouguer Anomaly, and De-trended Global Isostatic Residual values. Offshore data from a global gravity model provides context to the onshore measurements.
SPURS-1 deployed three autonomous Wavegliders on year-long missions in a 900 x 800-mile region of the subtropical North Atlantic. These platforms collected continuous, hour-averaged observations of near-surface and 6-meter depth salinity, temperature, currents, and atmospheric conditions. The dataset provides a detailed spatio-temporal characterization of processes maintaining a high-salinity ocean region, integrating in-situ and satellite measurements.
A long-term record of simulated land surface states and fluxes for the western United States, designed for drought assessment and water resources planning. The dataset is produced by NASA's Land Information System using the Noah-MP 3.6 model, driven by NLDAS-2 meteorological inputs. Outputs include soil moisture, snow water equivalent, evapotranspiration, and groundwater recharge at a 0.01-degree spatial resolution.
RAMSES II is a microwave-only retrieval algorithm that produces atmospheric profiles without a cloud-clearing process, enabling observations in all weather conditions. This Level 3 daily product provides a one-degree gridded synthesis of geophysical parameters from the NOAA-20 satellite's ATMS instrument, which scans across 22 channels from 23 to 183 GHz. The dataset includes profiles of temperature, water in all phases, and surface properties, with quality control flags provided for each variable.
240 granules per day provide global, all-weather atmospheric and surface observations from the NOAA-20 satellite. The RAMSES II algorithm processes microwave sounder data to retrieve temperature and water vapor profiles, precipitation, and surface properties without cloud clearing. Data is organized in 6-minute granules with an approximate 16-day orbit repeat cycle.
RAMSES II algorithm generates atmospheric profiles using only microwave observations from the ATMS instrument, enabling retrievals in cloudy conditions where infrared-based methods fail. This version 1 test dataset covers eight months across 2013 and 2015, specifically targeting seasonal and ENSO cycle comparisons. Each level 2 granule represents 6 minutes of data, with 240 granules produced daily from the satellite's 16-day repeat orbit.
CLIMCAPS V2.1 algorithm processes data from the Suomi-NPP satellite's CrIS/ATMS instruments to produce fixed Pressure Level (PLEV) atmospheric profiles. The dataset includes gas mixing ratios, column totals, surface values, tropopause properties, and relative humidity with per-field quality flags. Data is organized into 6-minute granules, with 240 produced daily, but has a latency of 3 to 7 weeks due to reliance on MERRA-2 reanalysis.
240 granules per day provide atmospheric profiles at fixed pressure levels, derived from the CLIMCAPS algorithm using full spectral resolution data from the Suomi NPP satellite's CrIS/ATMS instruments. The dataset includes gas mixing ratio profiles, column totals, surface values, tropopause properties, and relative humidity, with per-field quality flagging. Profiles are estimated from layer amounts and use MERRA-2 reanalysis as a first-guess, resulting in a data latency of 3 to 7 weeks.
Geoscience Australia Cruise 270 collected marine geological data from the Kenn Plateau off northeast Australia in 2004. The survey recorded 3090 km of multichannel seismic data, continuous multibeam-sonar swath-bathymetry, magnetic data, and twelve dredge hauls of sedimentary rocks. The data document the plateau's complex structure of thinned continental crust, rift basins, and volcanic features.
AGSO Cruise 149 (BANGSS) summarizes preliminary results from a 1994/95 marine geoscience program in Prydz Bay, Mac.Robertson Shelf, and the Kerguelen Plateau. The program aimed to understand modern sedimentary processes and the Plio-Pleistocene environmental history of the Antarctic margin. It was conducted by the Australian Geological Survey Organisation (AGSO), the Antarctic Co-operative Research Centre, and the Australian National Antarctic Research Expeditions (ANARE).
A 1965 marine geophysical survey by the Bureau of Mineral Resources collected combined gravity and seismic reflection data in the Timor Sea and Joseph Bonaparte Gulf. The survey recorded good-quality seismic reflections to 1.6 seconds and operated equipment simultaneously at boat speeds of 8 to 9 miles per hour. Results indicate a large offshore sedimentary basin containing at least 10,000 feet of post-Permian sediments.
Investigations into the coastal creek system augment limited prior water quality data from the Queensland EPA. The consolidated dataset supports a conceptual model of interacting processes for Keppel Bay's biogeochemistry. Data was collected under the Fitzroy agricultural contaminants project and Coastal CRC, hosted by the Australian Ocean Data Network.
