Hourly ambient ground-level ozone (O3) data in parts per billion from provincial air quality monitoring stations across Nova Scotia up to the end of 2024. The Government of Nova Scotia provides this data, which includes measurements from the Halifax Johnston station, established to replace the nearby Halifax Vogue station that ceased monitoring in 2017.
Nova Scotia is a national leader in reducing greenhouse gas emissions. The SolarHomes Program began in 2018 and provides rebates to homeowners for installing eligible solar projects, generating clean and affordable electricity. This dataset, published by the Government of Nova Scotia under an open license, likely tracks these installations.
Hourly ambient carbon monoxide (CO) data in parts per million from provincial air quality monitoring stations across Nova Scotia up to the end of 2024. The data is provided by the Government of Nova Scotia and was last updated on the platform in April 2026. The Sydney station was offline from October 15, 2024 to January 15, 2025, creating a gap in the data for that location.
Holdgate (1995) describes Permian glacial sediments extending south along the Loddon, Campaspe, Goulburn, and Ovens river valleys. This dataset defines their extent, compiled by GHD for a report on geological influences on groundwater flow. The Department of Energy, Environment and Climate Action published it under a CC-BY-4.0 license.
CSIRO produces daily Level 2P water quality data from Sentinel-3 OLCI satellite imagery under the eReefs Phase 5 project. The dataset includes reprojected full-resolution (approximately 300m-pixel size) maps of chlorophyll-a (Chl-a), colored dissolved organic matter (CDOM), and total suspended solids (TSS). Standard Level 1 quality flags and algorithm-specific out-of-range flags are provided for data quality control.
Several hundred global lakes and reservoirs have their surface water height tracked via satellite altimetry, potentially spanning a 25-year period from late 1992 to 2017. Derived from the G-REALM10 product, these pre-SWOT mission data support long-term trend analysis and modeling of human impacts on the water cycle. The dataset includes typical satellite data quality flagging and serves as a preparatory resource for users new to hydrological satellite data formats.
HOMAGE project data reconstructs global-mean sea level evolution and its contributing processes from 1900 to 2018. The reconstruction uses annual-mean tide-gauge observations aggregated via the virtual-station method, with contributions from thermosteric changes, glacier mass, Greenland/Antarctic ice sheets, and terrestrial water storage. Estimates combine GRACE satellite observations (2003-2018) with long-term in-situ data and models, providing confidence bounds for the planetary sea level budget.
Global ocean surface data from the SCATSAT-1 satellite's Level 2 products, providing ancillary fields interpolated to scatterometer observation points. This version 1.1 dataset includes ERA-5 wind forecasts, GPM IMERG precipitation estimates, and GlobCurrent surface currents at a nominal 12.5 km resolution, collocated in space and time. It represents a science-quality release funded by NASA's MEaSUREs program for evaluation by the International Ocean Vector Winds Science Team.
SWOT's Advanced Microwave Radiometer measures sea surface brightness temperatures at three specific frequencies: 18.7, 23.8, and 34 GHz. This Level 2 dataset processes those measurements to estimate key atmospheric variables like water vapor, cloud liquid water, and wind speed, which are used to correct range delays for the mission's primary altimeter. The data consists of discrete measurements along two tracks approximately 30 kilometers to the left and right of the satellite nadir, supporting the joint NASA-CNES mission's goal of high-resolution ocean and inland water mapping.
SWOT Level 2 Radiometer Brightness Temperatures and Troposphere GDR data provide atmospheric water vapor, liquid water content, and sea surface brightness temperatures from the Advanced Microwave Radiometer. The dataset is derived from measurements at three microwave frequencies (18.7, 23.8, and 34 GHz) along two tracks approximately 30 km from the satellite nadir. These geophysical estimates are used to correct altimeter range delays for the Surface Water and Ocean Topography mission, a joint NASA-CNES project launched on December 16, 2022.
104.8 GB of gridded daily maximum and minimum near-surface air temperature data covering 50°S to 79°N. The dataset was generated by Yuyu Zhou using a seamless land surface temperature dataset, a digital elevation model, and weather station observations with a specialized algorithm. It is intended for global studies in urban, climate, and hydrological research.
2020 daily maximum and minimum near-surface air temperature data at a 1 km resolution for the global land area between 50°S and 79°N. The dataset was generated by Yuyu Zhou using a seamless land surface temperature dataset, a digital elevation model, weather station observations, and a spatially varying coefficient model with sign preservation algorithm. It is a 104.4 GB TAR file published under a CC-BY-4.0 license.
Water quality observations for Ashmore Reef, a tropical marine reserve on Australia's North-west Shelf, document regional, lagoonal, and well water chemistry. The Australian Ocean Data Network compiled data from 1991, with an intensive monitoring program since 1999. Measurements include sea surface temperature, salinity, pH, and dissolved oxygen for oceanic waters, lagoons, and a freshwater lens.
Government and Municipalities of Québec provide an indicator of summer and winter surface water availability. The dataset combines sub-indicators for water sample pressure and low water level severity, calculated for both current and projected future climate conditions. The metadata was last updated on April 22, 2026.
Four glacial facies and two sediment drift deposits reveal the late Quaternary history of the East Antarctic Ice Sheet in the George V Basin. Chirp sub-bottom profiles, multi-channel seismic data, and sediment cores were integrated for this reconstruction. Radiocarbon ages from sediment cores link Facies MD2 to the Last Glacial Maximum.
Spire's constellation of 100 satellites collects GNSS signal data for atmospheric and Earth surface analysis. Products include Polarimetric Radio Occultation (PRO) measurements from May to November 2023 and GNSS Reflectometry (GNSS-R) data from May 2019 and December 2020 onward. The data is hosted by NASA Earthdata and originates from the European Space Agency (ESA).
6.7 ka of Arctic cold season climate proxy data from core STU-P1 in Svalbard Lake sediments. The dataset integrates hyperspectral imagery with X-Ray Fluorescence and Computed Tomography core scanning to characterize siderite concretions formed under lingering lake ice. It was produced by author van der Bilt for a publication available as a pre-print.
The Australian Ocean Data Network dataset examines sediment and water column nutrient concentrations across 12 shallow estuaries in southwest Western Australia. It analyzes relationships between sediment loads, sediment composition, and water quality, with sediment loads ranging from 0.2 to 10.8 kg m-2 year-1. The dataset was last updated on April 16, 2026.
The Murray Basin in Australia contains sandy clays deposited during the waning phase of an Oligocene-Middle Miocene marine transgression. This dataset, sourced from the Australian Ocean Data Network, includes a PDF/HTML document discussing the "Geera Clay equivalent" unit and its correlation with the Mologa weathering surface, proposing an age correlation with sequence boundaries at 13.8 or 10.5 million years ago. It also illustrates three pollen species and describes one new species, Tetrapollis campbellbrownii.
Core samples and groundwater from bores at Tresco in northern Victoria have been analysed for palynology and chemistry. The dataset, sourced from the Australian Ocean Data Network, describes the chemical evolution of an aquifer from fresh water to saline invasion between 400,000 and 18,000 years B.P. A marine explanation for the observed salinity patterns is reported as not possible.
