The Baseline Surface Radiation Network (BSRN) has provided high-accuracy surface radiation measurements across a global station network since 1992. Its central archive, the World Radiation Monitoring Center, stores radiation measurements with collocated meteorological observations and station metadata. BSRN is a project of the GEWEX Data and Analysis Panel aimed at detecting changes in Earth's surface radiation budget possibly related to climate change.
The Global Precipitation Measurement (GPM) mission is an international network of satellites providing global observations of rain and snow. It centers on a Core Observatory satellite with an advanced radar/radiometer system that measures precipitation from space and serves as a reference standard to unify measurements from a constellation of research and operational satellites. The mission was initiated by NASA and JAXA as a successor to TRMM.
Tor measurement project collecting performance data for public relays, bridges and onion services.
This dataset maps the network layer of the Invisible Internet Project (I2P), collected using the SWARM-I2P framework, which deployed I2P routers as mapping agents. It documents over 50,000 nodes with metrics such as bandwidth, latency, and uptime, plus network traffic records and geographic distribution. Node identifiers were anonymized. Data is available in CSV and TXT formats on Zenodo, with mapping scripts on GitHub.
The UK Environmental Change Network is the UK's long-term ecosystem monitoring and research programme, making regular measurements of air, soil, water, animals and plants across a network of sites since 1993. It provides free access to over two decades of detailed environmental data and instrumented research sites supporting environmental research and education.
The OONI Probe Tor test provides an automated way of examining whether Tor works in a tested network. It measures the reachability of Tor directory authorities, OR ports and obfs4 bridge addresses. The Tor network is described as free and open source, providing online anonymity, privacy and censorship circumvention.
An arXiv paper presenting a large-scale analysis of the Tor network using a crawler called Mimir, which collects and visits linked content. The authors report a dataset of pages from more than 25k sites and examine network topology, replicated content and content types.
TERN is Australia's Terrestrial Ecosystem Research Network. It provides model-ready terrestrial ecosystem data for research and describes itself as Australia's Ecosystem Observatory. Its Data Discovery Portal supports discovery, access and reuse of datasets from TERN observatory measurements, including site surveys, remote sensing, model-derived and in-situ sensor data. Data infrastructure includes a cloud-based virtual desktop and tools for data submission and landscape-scale dataset analysis.
A Tor Project page that summarizes resources the project provides for research on improving Tor design, monitoring the Tor network, and studying attacks and defenses for anonymous communication systems. It points researchers to data collection, analysis guidance and measurement and attack tools.
The Bureau Central de Magnétisme Terrestre provides ground-based geomagnetic observations and data products. It operates the French National Magnetic Observatory at Chambon-la-Forêt, a network of 18 overseas observatories and 11 repeat stations in metropolitan France. The site offers collected raw magnetic measurements and derived data products, with Digital Object Identifiers for variation and definitive data.
The Coastal Data Information Program (CDIP) measures, analyzes, archives and disseminates coastal environment data. It specializes in wave measurement, swell modeling and forecasting, and analysis of coastal environment data. CDIP is an extensive network for monitoring waves and beaches along United States coastlines, operated by the Ocean Engineering Research Group at Scripps Institution of Oceanography. It has produced a publicly-accessible environmental data database since 1975.
Dizzy is an open-source crawling and analysis system for onion services. It implements techniques to explore, update, check, and classify onion services at scale without overwhelming the Tor network. It was deployed in April 2021 and used to analyze more than 63.3 million crawled onion webpages, focusing on domain operations, web content, cryptocurrency usage, and web graph.
Personal page of Hakan Kardes, a principal scientist whose listed research interests include big data, record linkage, data mining, graph theory, social networks and Internet measurements. The page lists publications on topics such as connected component computation in MapReduce, address parsing and organization entity resolution.
The ICOS Carbon Portal is the data access point for the Integrated Carbon Observation System (ICOS), a network measuring atmospheric, ecosystem, and ocean greenhouse gas data across European member countries. It provides access to raw and processed measurement datasets, along with tools including STILT atmospheric transport modeling, DOI minting, and SPARQL querying to support climate change and emissions research.
The National Earthquake DataBase (NEDB) is a set of separate databases forming the national repository for raw seismograph data, measurements and derived parameters from Canadian and other seismograph networks. Its Parameters database holds information on Canadian earthquakes since the 16th century, and its Stations database holds seismograph station data.
Public-health research measuring harmful-content availability and searches on the Tor network.
Relay Search is a service in the Tor Project's metrics site for looking up Tor relays. The page renders search results, and the site's data is released under a CC0 no copyright declaration.
