OMI/Aura satellite data provides a 200-km-wide swath of total ozone column measurements, specifically collocated with the CloudSat track for the A-Train mission. This Level 2 subset includes ancillary parameters, terrain information, solar and satellite viewing angles, and quality flags. Its cross-platform presence on NASA EarthData and Data.gov signals its established use for multi-satellite atmospheric research.
Orbital data from the Suomi-NPP satellite's Ozone Mapping and Profiling Suite Nadir-Profiler instrument provides daily, global ozone measurements. The V8 algorithm reports ozone mixing ratios at 15 pressure levels between 50 and 0.5 hPa, along with total ozone column, UV aerosol index, and reflectivity data. Each granule covers the daylight portion of an orbit, with a spatial resolution of 250 km x 250 km and a latitude range of -82 to +82 degrees.
Orbital data from the Suomi-NPP satellite's OMPS Nadir-Profiler instrument provides daily global ozone profiles. The V8 algorithm reports ozone mixing ratios at 15 pressure levels between 50 and 0.5 hPa, along with total ozone column, UV aerosol index, and reflectivity measurements. Each daily granule contains data from approximately 14.5 orbits, with a spatial coverage from -82 to +82 degrees latitude and a footprint size of 250 km x 250 km.
OMPS-NPP L2 NM Sulfur Dioxide (SO2) Total and Tropospheric Column data provides retrieved SO2 column amounts from the OMPS Nadir-Mapper sensor on the Suomi-NPP satellite. A direct vertical column fitting algorithm retrieves total column and layer-specific amounts for the lower, middle, and upper troposphere, as well as the lower stratosphere. Data is provided in orbital swath granules with global coverage, a 2600 km swath width, and approximately 50 km resolution at nadir.
Version 6B of these data were introduced in July, 2020. The dataset contains three-dimensional convective latent heating profiles retrieved from GPM DPR KuPR precipitation observations. Latent heating variables are retrieved utilizing separate algorithms for tropics and mid-latitudes, based on monthly maps of precipitation types.
Buried Upper Devonian reef structures have been identified in the Lennard Shelf, Canning Basin. Analysis of seismic-record sections across one confirmed structure revealed a frequency increase interpreted as thinning sedimentary layers from differential compaction. Further analysis of sixteen selected seismic sections suggests the presence of four additional buried reef structures.
This dataset records 14 tropical cyclones that impacted Somali districts between 1984 and 2020, curated by the IGAD Climate Prediction and Applications Center (ICPAC). It maps the frequency of storm occurrences across specific administrative regions to support hazard and risk assessment. The data is provided in multiple geospatial and tabular formats including SHP, GEOJSON, and CSV.
Three submerged, living patch coral reefs covering 80 square kilometers were discovered in the southern Gulf of Carpentaria. The reefs were identified using multibeam swath sonar, seabed sampling, and underwater video by researchers associated with the Australian Ocean Data Network. This data was last updated in April 2026.

SCRN4L1RAD_CDROM is the gridded Level 1 radiance data product from the Nimbus-4 Selective Chopper Radiometer (SCR) experiment. It provides corrected radiance measurements from 16 infrared channels (2.3 to 15 micrometers) with a 25 km ground resolution, formatted in both daily 4°x10° grids and original orbit tracks. The data were produced by Oxford University's AOPP group under Principal Investigator Dr. John T. Houghton.
SCMRN5L1RAD is the Level 1 calibrated and geolocated radiance data product from the Nimbus-5 Surface Composition Mapping Radiometer. The instrument measured terrestrial radiation in two infrared bands and reflected solar radiation in a near-infrared band, enabling derivation of surface composition and sea surface temperatures. Data were collected over a 20-day period in December 1972 with a nadir ground resolution of 660 meters and a swath width of 800 kilometers.
Direct measurements of biogenic N2 fluxes show denitrification rates of approximately 1.3 mmol N2 m-2 day-1 in Port Phillip Bay sediments. The study found high denitrifying efficiencies of 75-85% at organic carbon loadings of 15-25 mmol m-2 day-1, returning nitrogen as biologically unavailable N2. This data was collected by the Australian Ocean Data Network and published in 2026.
Altered basalt, dolerite, and gabbro were collected from a previously unsampled section of the Macquarie Ridge between 47° and 48° S. These rocks are petrographically and geochemically similar to MORB-like suites found further south, linking the northern ridge geologically to the rest of the feature. The dataset, provided by the Australian Ocean Data Network, includes dredged sedimentary rocks derived from both oceanic ridge and continental New Zealand sources.
TRMM_TMPA_LandSeaMask Version 2 is a static land/sea mask regridded to a 0.25x0.25 degree resolution for use with GPCP, TMPA, and IMERG precipitation products. The mask was originally produced by NOAA at SSEC in the 1980s and was restructured into a CF-compliant netCDF4 format by NASA's Terrestrial Information Systems Laboratory. Version 2 was created in May 2019 to resolve inaccuracies detected in coastal regions.
This geospatial dataset catalogs 14 tropical cyclones that impacted Somali regions between 1984 and 2020. Produced by the IGAD Climate Prediction and Applications Center (ICPAC), the data maps the frequency of cyclone occurrences across specific administrative boundaries. It provides historical records for events ranging from 1984's Tropical Cyclone 1A to 2020's Tropical Cyclone Gati.
A proposal outlines plans for deep riser drilling up to 2500 meters below the seafloor on the Lord Howe Rise continental ribbon. The project, led by Geoscience Australia and JAMSTEC, aims to recover Cretaceous and older sediments to study tectonic and climatic history. Preparatory seismic surveys were conducted in 2016, with drilling planned for 2019 or 2020.
Deep riser drilling plans target a 2500-meter core through Cretaceous sediments and basement rocks on the Lord Howe Rise continental ribbon. Geoscience Australia and JAMSTEC lead this international effort, with drilling proposed for 2019 or 2020 to recover a >100-million-year geological record. Preparations included 2D seismic surveys in 2016 and 2017 to map crustal structure and acquire geotechnical data.
MLS/Aura Level 2 Ozone (O3) Mixing Ratio V004 (ML2O3) is a standard satellite product from NASA's EOS Aura Microwave Limb Sounder. The dataset provides near-global ozone profiles from 261 to 0.0215 hPa, with data spaced roughly 165 km along the orbit track. It is stored in HDF-EOS5 format and was last updated in March 2026.

The data version is 5.0, with profiles spaced 1.5 degrees along the orbit track and a useful vertical range from 261 to 0.0215 hPa. This dataset is produced by the National Aeronautics and Space Administration and stored in HDF-EOS5 format.
The National Drought and North Queensland Flood Response and Recovery Agency published a list of 14 Local Government Areas declared disaster areas. These LGAs were activated for Category C assistance under joint Commonwealth-State funding arrangements due to monsoon trough flooding from January 25 to February 14, 2019.
