NASA's GOES-R PLT dataset provides surface reflectance and total optical depth measurements from Ivanpah Playa, Nevada. The data was collected during a 2017 field campaign using an Automated Solar Radiometer and a portable spectroradiometer to validate post-launch calibration of the ABI and GLM instruments. However, the full dataset appears limited, with data files only confirmed for two specific days in March 2017.
Acoustic and video data from playback experiments investigating male-male competition in white-headed langurs. The dataset includes sound files, video clips, and analysis results focusing on the temporal structure of loud calls. It was authored by Yinshu Liu and last updated on 2026-04-27.
St. Kitts and Nevis trade data compiled by the World Bank Group, part of the Transparency in Trade Initiative.

It was last updated on 2026-04-28 and is provided in CSV format under a CC-BY-4.0 license.
Debt statistics from the World Bank provide a detailed picture of debt stocks and flows for St. Kitts and Nevis. The data likely contains quarterly external debt figures and public sector debt details, including valuation methods and instrument types. The dataset was last updated on 2026-04-28 and is licensed under CC-BY-4.0.
World Bank Group data on private sector activity and trade for St. Kitts and Nevis. The dataset aggregates indicators from sources including the Private Participation in Infrastructure Project Database, Enterprise Surveys, Doing Business Indicators, IMF Balance of Payments, and UNCTAD. It was last updated on 2026-04-28.
World Bank Group data aggregates science and technology indicators for St. Kitts and Nevis. The dataset likely contains metrics on research and development, scientific publications, high-technology exports, royalty fees, and intellectual property. It was last updated on 2026-04-28 and combines data from sources including UNESCO, the U.S. National Science Board, and the World Intellectual Property Organization.
St. Kitts and Nevis public sector data from the World Bank Group, last updated on 2026-04-28. It includes World Bank staff assessments of country performance in economic management, structural policies, social inclusion, and public sector institutions. The dataset also incorporates government finance statistics from the International Monetary Fund and tax policy indicators from various sources.
Hourly temperature profiles from eight heights on a tower in the Tapajos National Forest, Brazil, spanning January 2002 to January 2006. Co-located measurements include CO2 and H2O concentration profiles, canopy storage, and eddy flux data from two levels, alongside other meteorological parameters. The dataset is associated with a Ph.D. thesis from Harvard University and is hosted by multiple platforms including NASA EarthData.
Data Sheet 2 contains results from a mixed-methods intervention study on vocal performance anxiety management. The study by Qin Cong recruited 60 undergraduate vocal performance majors and collected quantitative and qualitative data across three time points: pre-intervention, post-intervention, and 3 months post-intervention. The dataset was last updated on 2026-04 27.
Qin Cong's dataset contains results from a mixed-methods intervention study on vocal performance anxiety management. The study involved 60 undergraduate vocal performance majors, with data collected at three time points over a 12-week intervention and a 3-month follow-up. The dataset includes quantitative measures of anxiety, performance quality, resilience, self-efficacy, and heart rate variability, plus qualitative reflective journals.
Cigarette butts are the most common type of litter despite contributing little to total volume. Plastic waste items are high in both number and volume, while glass is the least prevalent litter type. This dataset from the Queensland Department of Environment, Tourism, Science and Innovation was last updated in May 2026.
1989 data from the FIFE experiment provides site-averaged daily neutron probe soil moisture measurements. This dataset contains processed, site-averaged values for soil moisture content collected during the 1987-1989 field campaign. It is part of a larger Earth science study focused on land surface processes.
36 participants were exposed to music with or without infrasound (~18 Hz) in a 2x2 between-subjects design. The dataset likely contains self-reported mood measures and salivary cortisol levels collected pre- and post-exposure, showing links between infrasound and negative affective states. The data was authored by Kale R. Scatterty and last updated on 2026-04-27.
Four years of eddy flux measurements from January 2002 through January 2006 document carbon dioxide and water vapor exchange in a primary Amazon rainforest site. The data were collected by researchers from Harvard University and ORNL using tower-mounted gas analyzers and sonic anemometers at two heights. A companion Ph.D. thesis by Hutyra (2007) provides detailed analysis of carbon and water exchange processes.
Submersed aquatic vegetation (SAV) data was collected over Buttermilk and Plymouth Bays in Massachusetts during September 2010. The dataset results from a collaborative campaign using the CHARTS airborne hyperspectral/lidar system, supported by extensive ground truth sampling including bathymetry, diver surveys, and water column measurements. The data is managed by NASA and originates from a joint operation by the U.S. Army Corps of Engineers and the U.S. Naval Oceanographic Office.
FIFE experiment data from 1989 provides site-averaged measurements of land-atmosphere energy exchange in 30-minute intervals. The dataset likely contains variables related to atmospheric radiation and soil heat flux. It represents a key product from a multi-investigator field campaign focused on surface processes.
Site Averaged Neutron Soil Moisture Data: 1988 (Betts) contains daily site-averaged neutron probe soil moisture measurements from the 1987-1989 FIFE field campaign. The dataset includes only measurements from the 1988 season. NASA is the authoritative organization responsible for this data.
30-minute average variables were collected from May 27 to October 16, 1987, as part of the FIFE experiment. This time series data set contains site-averaged product data from multiple principal investigators during the 1987-1989 field campaign. It likely contains measurements related to atmospheric radiation, soil heat flux, and land surface interactions.
Site Averaged Gravimetric Soil Moisture Data from the 1987-1989 FIFE experiment provides daily averaged soil moisture measurements from multiple field sites. The dataset contains data from May 20, 1987, through August 12, 1989, with samples averaged first by site and then by day. It supports research on land-atmosphere interactions and soil hydrology.
NASA's 1988 Betts dataset provides site-averaged atmospheric and soil flux measurements from the FIFE field campaign. It contains data aggregated in 30-minute intervals for the single year of 1988. The dataset was collected by multiple principal investigators to study land-atmosphere interactions.
