GRIM4-S global gravity field models represent Earth's gravitational potential using fully normalized spherical harmonic coefficients. The series comprises four solutions (GRIM4-S1 to S4) derived from tracking data of 27 to 32 satellites. These models were produced by the SCIOPS organization.
A collection of maps identifying hydrothermally altered rocks in the central and southern Basin and Range province of the United States. The maps were compiled using ASTER satellite data and IDL logical operator algorithms by the CEOS_EXTRA organization. They delineate four alteration types: hydrothermal silica-rich, propylitic, argillic, and phyllic rocks.
Replication data used to generate figures for a study on Arctic ozone depletion and mid-latitude ozone losses. The dataset likely contains model outputs related to heterogeneous halogen chemistry following a hypothetical regional nuclear conflict. It was authored by Yook, Simchan and hosted on Harvard Dataverse, with a last recorded update in April 2026.
Microzooplankton data focuses on ciliates, parameterizing their abundance, biomass, cell size structure, biodiversity, and production. The dataset was produced by the SCIOPS organization for the Marine Productivity programme to support model development. Specific temporal coverage and data volume are not provided.
Mid-June through Labor Day each swim season, personnel from the New Hampshire Department of Environmental Services monitor and sample approximately 170 inland and 15 coastal public bathing beaches. Inspectors collect two to three bacteria samples per beach and assess on-site facilities and surrounding areas for health threats. The program involves conferring with lifeguards and the public to address concerns.
Over 20,000 individual Calanus copepods are identified to species level, including problematic early developmental stages like nauplii and early copepodites. The data was generated by the SCIOPS organization using an automated system based on a modified method from Lindeque et al. (1999). The program underpinned the Broad Scale Survey and Hirst et al. projects.
Auroral spectrograph data captures optical emissions from 420 to 740 nanometers with a spectral bandwidth of 0.6 nm. The instrument uses a 512 x 512 pixel CCD camera and a fish-eye lens with a 180-degree field of view, enabling a sampling rate of a few seconds per image. The dataset is produced by the SCIOPS organization for collaborative study with the EISCAT Svalbard Radar and other ground-based observations.
Approximately 2500 scenes of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data are held by the Australian Antarctic Data Centre. Over 1500 of these scenes are Level 1B data, which have been radiometrically calibrated and geometrically resampled. The data originates from NASA's ASTER instrument on the Terra satellite.
Kaggle hosts this dataset on IoT node thermal performance. The data likely contains measurements from calorimetric analysis of heat dissipation. The author, organization, and specific data volume are unknown.
Saarland, Germany, hosts this geospatial dataset mapping roof surface potential for solar thermal energy. The data originates from the state study 'Wärmewende im Saarland – Status quo, potentials and fields of action' and is provided by the Bundesamt für Kartographie und Geodäsie via an OGC WFS interface. It was last updated on March 19, 2026.
Data from 1989 measuring the physical structure and optical transmissivity of Antarctic sea ice. The dataset includes depth-dependent profiles of temperature, salinity, density, and heat capacity, alongside measurements of UV and visible light transmission. It was collected by the organization SCIOPS to study the effects of UV radiation on polar ecosystems and seasonal ice changes.
NASA Earthdata hosts physiological measurements from 23 non-incubating Adelie penguins subjected to environmental stresses. The dataset contains time-series observations of heart rate, blood oxygenation, cytochrome oxidase redox state, and peripheral blood flow, recorded via a visible/near-infrared optical spectrometer. Data was collected by the SCIOPS organization and last updated in December 1999.
Reduced raw geodetic optical observations from the Optical Beacon System instrument flown on the GEOS-2 (Explorer 36) satellite. The dataset contains 1689 data records covering an eight-month period from February to October 1968. The principal investigator for the experiment was R. E. Williston from APL.
Genetic analysis of the only known continental Antarctic population of the moss Pohlia nutans, found on the geothermally heated ground of Mount Rittmann. Specimens from several moss patches within two sites totaling 80 m2 were analyzed using RAPD and DNA sequencing of the 18S-26S ITS region. The dataset was produced by the organization SCIOPS and last updated in January 1999.
Sediment cores from Florida Bay provide measurements of bulk density, water content, particle size distribution, and lead-210 activity for radioactive dating. The dataset was compiled by the CEOS_EXTRA organization and last updated in June 1997. It enables analysis of sediment composition and accumulation rates over time.
Temperature readings from all five bolometers on the Explorer-7 satellite, measuring solar, reflected, and terrestrial radiation. The dataset covers the mission from October 19, 1959, to June 4, 1960, with data restored from original IBM 7094 magnetic tapes. Principal Investigator Verner E. Suomi from the University of Wisconsin led the experiment.
Explorer-7 satellite data contains nighttime temperature values measured by a white sensor designed for terrestrial radiation. The dataset covers the mission period from November 15, 1959, to May 24, 1960, and was produced by Principal Investigator Verner E. Suomi of the University of Wisconsin. It represents the first set of Earth-looking radiation data collected from space.
Phytoplankton characteristics and bloom phenomena data compiled from four major monitoring programs in the New York Harbor Estuary and New York Bight. The dataset was created by SCIOPS for the NY/NJ Harbor Estuary Program, with a last recorded update in 1995. It addresses chlorophyll a, species biomass, and environmental factors contributing to algal blooms.
700-meter resolution data from the ADEOS satellite's Ocean Color and Temperature Scanner provides normalized water-leaving radiance at five visible wavelengths and aerosol properties at three near-infrared bands. The dataset was produced by Japan's National Space Development Agency (NASDA) from the short-lived ADEOS mission, which operated from August 1996 until its failure in June 1997. It contains geophysical parameters derived from Level 1B data, including aerosol optical thickness and correction factors.
Normalized water-leaving radiance at 412, 443, 490, 520, and 565 nm, along with aerosol radiance and optical thickness data, are provided in this Level 2 product. The dataset was produced by the National Space Development Agency of Japan (NASDA) from the Ocean Color and Temperature Scanner (OCTS) onboard the ADEOS satellite. Data collection spans from the satellite's launch on August 17, 1996, until mission termination on June 30, 1997.
