Global monthly Normalized Difference Vegetation Index (NDVI) data provides a 22-year satellite record of terrestrial vegetation changes from July 1981 to December 2002. The dataset from the Global Inventory Modelling and Mapping Studies (GIMMS) is processed to reduce variations from calibration, view geometry, volcanic aerosols, and orbital drift. It was generated for the International Satellite Land Surface Climatology Project (ISLSCP) Initiative II collection to support climate and biogeochemical modeling.
Hydrology data from the RV Investigator voyage IN2025_E01 collected between February 19 and March 01, 2025. Samples were taken from Niskin bottles at various depths during CTD deployments and analyzed for salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium. The processed dataset is archived at the CSIRO National Collections and Marine Infrastructure Information and Data Centre.
Monthly minimum and maximum temperature, precipitation, and potential evapotranspiration data were derived for 1,469 watersheds in the conterminous United States. The data spans 40 years from 1951 to 1990 and is linked to the USGS Hydro-Climatic Data Network streamflow database. Temperature and precipitation estimates were generated using the PRISM climate analysis system, while potential evapotranspiration was calculated using the Hargreaves-Samani method.

Environment Protection Authority validated meteorology data supports air quality assessment and management decisions for South Australian airsheds. The dataset includes wind direction measurements requiring vector averaging for longer-duration calculations. Data is provided by the EPA under a CC-BY-4.0 license and was last updated in April 2026.
South Australian airsheds are monitored by the Environment Protection Authority to assess air quality and inform management. This dataset contains validated meteorology data for the Northeastern Adelaide region, with wind direction requiring vector averaging for longer-duration calculations. The data was last updated on 2026-04-28.
Data from 1939 to 1990 records above- and below-ground net primary production (NPP) and biomass dynamics for a semiarid shortgrass prairie in Colorado's Central Plains Experimental Range. The dataset includes nine files with measurements from untreated, irrigated, fertilized, and combined treatment plots, plus long-term climate records from 1912. It was revised and is maintained by ORNL_CLOUD.
Badkhyz Nature Reserve in Turkmenistan provides a long-term record of above-ground plant biomass and climate data from 1941 to 1982. The dataset includes monthly biomass harvest measurements from 1948-1963 and annual peak biomass measurements from 1964-1982, alongside corresponding monthly and annual climate observations. Data files are in text format and were originally published in 1998, with documentation revised more recently.
Three text files contain monthly biomass measurements from July 1984 to November 1994 for an ungrazed tropical dry savanna grassland in Nairobi National Park, Kenya. The dataset includes net primary productivity estimates for 1984-1986, with above-ground NPP averaging 1,004 g/m2/yr, and complementary climate data from 1969-1989. It was published by ORNL_CLOUD and is available on multiple platforms including NASA Earthdata and Data.gov.
NPP Grassland: Konza Prairie, USA, 1984-1990, R1 contains three ASCII files with above-ground biomass and productivity data for a humid temperate tall-grass prairie in Kansas. The dataset provides separate data for burned and unburned treatments from 1975 to 1990, alongside climate records from 1891 to 1988. It is part of the Konza Long Term Ecological Research (LTER) program, built on a fully replicated watershed-level experimental design in place since 1977.
November 1970 through December 1971 data from a lower montane rainforest in Papua New Guinea. This dataset contains net primary production (NPP) component data, including litterfall, LAI, biomass, and nutrient content, alongside climate records of rainfall and temperature. The study was conducted by ORNL_CLOUD across five distinct forest stands.
230 grams per square meter per year was the average total net primary productivity for eight coastal tundra vegetation communities at Point Barrow, Alaska. This dataset contains three files with biomass, leaf area index, and NPP estimates for different plant growth forms, plus local climate data, collected during the 1970-1972 growing seasons. The research was conducted as part of the International Biological Program's U.S. Tundra Biome study, with measurements taken at 10-day intervals using harvest and gas exchange methods.
Five text files document monthly above-ground and root biomass measurements from a mixed prairie at Canada's Matador Field Station, alongside climate records from 1968-1972 and a longer-term Swift Current weather series from 1938-1990. The data, associated with ORNL_CLOUD, includes calculated annual net primary productivity values for a specific study section. Its presence on NASA EarthData and Data.gov signals its established use in ecological research.
Environment Protection Authority validated meteorology data for assessing air quality in South Australia. The dataset includes wind direction, which requires vector averaging for longer-duration calculations. Last updated in April 2026, it supports management decisions for the North western Adelaide airshed.
The Environment Protection Authority (EPA) monitors South Australian airsheds to assess air quality and guide management decisions. This dataset contains validated meteorology data for the Spencer Gulf region, including wind direction requiring vector averaging for longer-duration calculations. The data was last updated on 2026-04-28.
Southern Adelaide region validated meteorology data collected by the Environment Protection Authority (EPA) to assess air quality and guide management decisions. The dataset includes wind direction data requiring vector averaging for longer-duration calculations. It was last updated on 2026-04-28.
Validated meteorology data for the Northern Adelaide region, collected by the South Australian Environment Protection Authority (EPA). Monitoring was suspended in 2020 and recommenced in 2022. The dataset is provided in CSV format under a CC-BY-4.0 license.
WRF-STILT model outputs provide gridded surface influence footprints for the NOAA Barrow Alaska Observatory receptor. The dataset covers 12 selected years within a 30-year study period from 1982 to 2011, focusing on the late summer to autumn window each year. These simulations are part of a retrospective analysis to link atmospheric composition changes with shifts in Arctic ecosystem structure and function.
PREFIRE Level 1A data provides calibrated spectral radiance measurements from a push broom spectrometer aboard the PREFIRE-SAT1 CubeSat. It captures mid- and far-infrared radiation across 63 channels from approximately 5 to 53 µm, focusing on polar regions to fill gaps in the global energy budget. This ungeolocated radiance data serves as the input for generating geolocated Level 1B products.
PREFIRE's dual CubeSats carry push broom spectrometers with 63 channels measuring mid- and far-infrared radiation from 5 to 53 µm, a spectral range where most polar emissions occur but which has not been measured on a large scale. This Level 1B dataset provides calibrated and geolocated spectral radiance, processed using satellite telemetry and a digital elevation map, to fill knowledge gaps in the global energy budget. The data is used to analyze the polar radiative budget and serves as input for Level 2 products like top-of-atmosphere flux, surface emissivity, and atmospheric properties.
