February 2000 data from the 11-day STS-99 Space Shuttle Endeavour mission. This dataset provides a near-global digital elevation model (DEM) of Earth's landmass between 60° N and 56° S latitude, generated via radar interferometry by NASA and partner agencies. The Version 3 global 3 arc second (~90 meter) product was derived from higher-resolution data and has voids filled using supplementary topographic datasets.
NASA Shuttle Radar Topography Mission (SRTM) Version 3.0 global 1 arc second (~30 meter) number product. The data results from a collaborative effort by NASA, the National Geospatial-Intelligence Agency, and German and Italian space agencies, collected during the STS-99 Space Shuttle Endeavour mission launched on February 11, 2000. It provides a near-global digital elevation model (DEM) covering land between 60° N and 56° S latitude, representing approximately 80% of Earth's total landmass.
20-minute-resolution solar wind plasma parameters from the Soviet Vega 1 mission's interplanetary cruise to Comet Halley. Proton flow speeds, densities, and temperatures were derived by fitting energy spectra to convecting Maxwellian models, with parameters calculated using both linear and logarithmic fitting methods. The data were collected by NASA and have coverage gaps between April 1985 and August 1986.
MCD18A2 Version 6.2 provides daily global estimates of Photosynthetically Active Radiation (PAR) at 1-kilometer pixel resolution, with data points every 3 hours. The National Aeronautics and Space Administration (NASA) produces this combined MODIS Terra and Aqua product using a prototyping algorithm that incorporates multi-temporal signatures and look-up tables for aerosols and clouds. Improvements in this version include the use of shortwave infrared bands to reduce uncertainty in cloud- and snow-covered pixels and an updated multispectral algorithm.
The Vega 2 mission collected solar wind plasma parameters during its interplanetary phases en route to Comet Halley. This dataset provides proton flow speeds, densities, and temperatures at a 20-minute resolution, derived from fitting energy spectra to convecting Maxwellian models. The data includes two parameter sets ('linear' and 'log') and was produced by NASA, with coverage spanning specific periods in 1985 and 1986.
The Dedication Woodland Scheme was introduced in 1947 to encourage landowners to retain land in forestry and adopt good practice. Basis III was added in 1974, providing grants for new planting and broadleaf supplements, before the scheme closed to new applicants in 1981. This dataset from the Government Digital Service records land under this historical UK forestry policy.
NASA Shuttle Radar Topography Mission (SRTM) Global 3 arc second V003 is a near-global digital elevation model (DEM) derived from radar interferometry. The data was collected during the STS-99 Space Shuttle mission in February 2000 and covers land between 60° N and 56° S latitude, accounting for approximately 80% of Earth's landmass. Version 3 data was produced by NASA and partner agencies, with voids filled using supplementary topographic datasets like ASTER GDEM.
NASA's Shuttle Radar Topography Mission (SRTM) generated a near-global digital elevation model (DEM) covering 80% of Earth's landmass between 60° N and 56° S. The data was collected over 11 days in February 2000 from the Space Shuttle Endeavour using radar interferometry at an altitude of 233 kilometers. This global 30 arc second (~1,000 meter) product is a result of collaboration between NASA, the National Geospatial-Intelligence Agency, and German and Italian space agencies.
MCD18C2 Version 6.2 provides global estimates of Photosynthetically Active Radiation (PAR) every 3 hours at a 0.05-degree resolution. The National Aeronautics and Space Administration produced this combined Terra and Aqua MODIS product, which was last updated in March 2026. PAR measures incident solar radiation in the 400-700 nanometer spectrum, a critical variable for land-surface modeling.
MCD18A1 Version 6.2 is a Moderate Resolution Imaging Spectroradiometer (MODIS) combined Terra and Aqua satellite product providing Downward Shortwave Radiation (DSR) estimates. The dataset is produced daily at 1 kilometer pixel resolution with 3-hourly DSR arrays and is generated by the National Aeronautics and Space Administration (NASA). The latest update for this record was on 2026-03-12.
SynthDocBench is a fully synthetic benchmark for evaluating vision-language models on complex, multi-page PDF documents. It was created by ServiceNow-AI using an LLM pipeline to generate realistic reports with embedded D3.js charts and rich layouts. The dataset page was last updated on 2026-05-23.
National Archives data details the number of calls received and answered by its public and staff Contact Centre during the 2018-19 and 2019-20 periods. The dataset is provided by the Government Digital Service as supplementary transparency information beyond standard commitments. It is available as an Excel file under a CC-BY-4.0 license.
Wazobia Labs is building the first gold-standard benchmark for evaluating AI models on Nigerian Pidgin. The dataset aims to provide culturally verified test sets, including a sarcasm corpus, to assess nuanced language understanding. Its target release is Q3 2026 under a CC-BY-4.0 license.
Biosiliceous sediments sampled from a submarine valley system on the continental shelf of East Antarctica contain intervals of ripple cross-lamination interspersed with massively bedded units. Radiocarbon dates from a core on the Mac.Robertson Shelf indicate the most intensely cross-laminated sediments were deposited between 6,000 and 3,500 years before present. The dataset is hosted by the Australian Ocean Data Network.
Over the past 15 years, Japanese, Australian, and Russian expeditions collected approximately 30,000 km of bathymetric data, 6,000 km of sidescan sonar data, and more than 250 sediment grab and core samples in Prydz Bay, East Antarctica. These data were compiled by the Australian Ocean Data Network to produce surficial sediment, bathymetric, and geomorphological maps of the region.
Danbooru's general-category tag wiki pages are stored in a single-file SQLite database. The database includes a sqlite-vec virtual table holding 640-dimensional embeddings of each cleaned wiki body text. JackBinary created this resource, which was last updated on Hugging Face in May 2026.
Kool and Nichol developed a four-dimensional (3D × time) biophysical dispersal model to simulate marine larval movement. The model simulated massive numbers of larvae to study connectivity patterns among Commonwealth Marine Reserves in Australia's northwest region. This work was published in 2015 in Environmental Modelling & Software.
A repository mirroring polyglot language models, hosted on Hugging Face by ndandanov. The description notes that as of the last update on 2026-05-21, only English and Bulgarian have all model types available, with other languages potentially having partial support. The repository serves as a centralized hub and encourages community contributions to add missing models.
