Six wavelengths (510, 600, 675, 745, 869, and 997 nm) provide multi-spectral aerosol extinction coefficients from the OMPS Limb-Profiler sensor on the NOAA-N21 satellite. Data is collected from the ground up to about 80 km with a vertical resolution of approximately 1.8 km, covering about 14.5 global orbits per day. This product, which replaces the previous single-wavelength AER675, is generated via a neural network for near-real-time processing and is stored in HDF5 format.
A 2006 marine seismic survey (GA302) recorded data from 50 sonobuoys over the Capel and Faust Basins, 800 km east of Australia. The data, collected for Geoscience Australia's Big New Oil programme, includes interpreted P-wave velocity estimates for sedimentary layers, gravity, and magnetic anomaly data. These were used to model sediment thickness, which may reach up to 5 km in some areas.
The George V Shelf in East Antarctica between longitudes 142°E and 146°E is the focus of this multidisciplinary analysis. The dataset results from a hierarchical benthic habitat mapping study integrating seismic profiles, multibeam sonar, oceanographic data, and sediment sampling. It was published via the Australian Ocean Data Network and last updated on June 5, 2026.
SONEX_Aerosol_AircraftInSitu_DC8_Data_1 contains in-situ aerosol measurements from the NASA DC-8 aircraft during the 1997 SASS Ozone and NOx Experiment. The international campaign investigated the impact of subsonic aircraft emissions on atmospheric composition in the North Atlantic Flight Corridor. Instrumentation included condensation nuclei counters, particle impactors, and spectrometers to measure aerosol concentration and chemical composition.

The data originates from the 1997 Subsonics Assessment Ozone and NOx Experiment (SONEX), an international mission sampling the North Atlantic Flight Corridor to assess the impact of aircraft emissions on atmospheric composition. The dataset is part of a larger payload that included measurements of NOx, ozone, aerosols, and other trace gases.
October-November 1997 data from the SASS Ozone and NOx Experiment (SONEX) campaign, measuring in-situ atmospheric composition from a NASA DC-8 aircraft. The dataset captures trace gases, aerosols, and meteorological parameters to assess the impact of subsonic aircraft emissions on upper tropospheric/lower stratospheric chemistry. Flights were conducted from staging locations in Bangor, Maine, and Shannon, Ireland, targeting the North Atlantic Flight Corridor.
From November 5 to December 19, 2015, this dataset contains brightness temperatures measured by the Conical Scanning Millimeter-wave Imaging Radiometer (CoSMIR) aboard the NASA DC-8 aircraft. It provides data from nine channels at frequencies including 50.3, 52.8, 89.0, 165.5, and 183.31 GHz, collected during the Olympic Mountains Experiment (OLYMPEX) for the Global Precipitation Mission (GPM). The primary data files are in HDF-5 format, accompanied by PNG browse imagery showing time series plots.
NASA's Iowa Flood Studies (IFloodS) campaign produced this dataset by merging rain gauge measurements with satellite microwave data from the DMSP F15 and F16 platforms. The Probability Matching Method was used to generate near-real-time rain rate estimates over eastern Iowa from April 23 to June 30, 2013. This dataset supports the validation of satellite-based precipitation products from the Global Precipitation Measurement (GPM) mission.
ISLSCP II UNH/GRDC composite runoff data integrates simulated water balance model estimates with monitored river discharge measurements using a data assimilation technique. The dataset contains 11 data files and 1 changemap file comparing the ISLSCP II land/water mask to the original data. This approach aims to preserve spatial specificity while being constrained by more accurate discharge observations.
This dataset is a subset of the Global Hydrographic dataset (GGHYDRO) Release 2.2, created for the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA). It provides 19 global raster layers at 1-degree resolution, detailing terrain types, drainage basins, cryosphere features, and water/ice runoff. The data is managed by ORNL_CLOUD and was last updated on a platform in March 2026, though a conflicting date of 1990 exists.
Marine National Facility (MNF) Processed Underway Parquet Data contains quality-controlled navigation, oceanographic, and atmospheric measurements from research voyages. The data, processed and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre, is supplied to the Australian Ocean Data Network and other global repositories. Data points are available at 5-second intervals.
Global and North American environmental driver data standardized for carbon cycle model intercomparison. The dataset contains 3,152 netCDF-4 files providing gridded climatology variables, atmospheric CO2, nitrogen deposition, land cover, and soil characteristics from 1801 to 2010. It was compiled by the Oak Ridge National Laboratory Distributed Active Archive Center for the North American Carbon Program's Multi-Scale Synthesis and Terrestrial Model Intercomparison Project.
INSPIRE-compliant nationwide occurrence data for glacier habitat types in Germany, compiled by the Federal Office for Nature Conservation. The information generally covers the period from 2000 to 2012, sourced from federal and state-level data for the national Habitats Directive report. Specific temporal coverage for individual habitat types may vary.
OMPS-NPP L1G LP Radiance EV Wavelength-Altitude Grid swath orbital 3slit product contains calibrated earth-viewing radiances from the Ozone Mapping and Profiling Suite Limb-Profiler sensor aboard the Suomi-NPP satellite. It measures radiances across a broad spectrum from 280 nm to 1000 nm, providing vertical profiles from ground level up to about 80 km altitude. The data offers global spatial coverage with approximately 14.5 orbits per day, each capturing three limb profiles spaced roughly 250 km apart.
The Amazonian Region Micrometeorological Experiment (ARME) data contain micrometeorological measurements from the Amazon rainforest. The dataset includes four data types: climate, precipitation interception, micrometeorology, and soil moisture, focusing on energy balance and evapotranspiration. One key finding from this NASA experiment was that tropical forest does not experience water stress during periods when evapotranspiration is at the potential rate.
RAMSES II algorithm generates Level-2 geophysical retrieval products from the Suomi NPP Advanced Technology Microwave Sounder (ATMS).

Rainfall estimates for southern Africa provide 10-day precipitation data from 1999 to 2001, produced by the USAID Famine Early Warning System (FEWS). The dataset combines satellite data from Meteosat-7, SSM/I, and AMSU with quality-controlled rain gauge measurements from around 1000 WMO stations. It is stored as 8 km resolution binary raster images in an Albers projection.
Soil moisture gravimetric data were collected from multiple stations across the FIFE study area. The dataset was created by NASA to characterize spatial and temporal patterns of soil water content, validate remote sensing measurements, and evaluate ground and aerial measurement methods. Data collection concluded in 1989, with metadata last updated in 2026.

The dataset contains total column ozone, UV aerosol index, Rayleigh-corrected surface reflectivity, and sulfur dioxide index values derived from the best-matched satellite field-of-view for each site. Data were produced by NASA's Laboratory for Atmospheres and are stored in ASCII format.
