title: RPKIViews 2021 Amalgamation

description: The RPKI is an infrastructure which helps secure the global Internet routing system. RPKIViews.org is a global multi-perspective data collection initiative. This dataset is an amalgamation of 46,507,392 signed RPKI objects extracted from 26,273 RPKIViews.org snapshot archives discovered between December 6th, 2020 and December 31st, 2021 inclusive. The objects originally were fetched from publication servers which were discovered using the Trust Anchor Locators of the following Regional Internet Registries: AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC. 

The median RPKI object size in this dataset is 1,908 bytes and the total cumulative size of all objects in uncompressed form is 78,1 gigabytes.

Not all objects contained within this dataset comply with the requirements of modern day RPKI relying party implementations.

The following file naming scheme is used for the tar archive members: every filename is the URL-safe Base64-encoded SHA-256 message digest of the object's ASN.1 encoded content. For performance reasons, the directory hierarchy is constructed using the last few bytes of the filename. The file's recorded last-modification timestamp is constructed following the procedure outlined in RFC 9589. The tar achive adheres to the IEEE Std 100.2 POSIX.2 "USTAR" interchange format and is compressed in Zstandard (RFC 8878) form.

title: USGS 3D Hydrography Program (3DHP) - 2025 Staged Product (FY26 Release)

description: The 3D Hydrography Program (3DHP) data is an integrated, National, 3D-enabled hydrographic dataset derived from the USGS 3D Elevation Program (3DEP) data. For areas where Elevation-derived Hydrography (EDH) has not yet been collected, 3DHP data is supplemented by vector data from the National Hydrography Dataset (NHD). As further EDH data is collected, it will replace the NHD data in those areas. 3DHP data ingested from EDH sources includes catchments and flowline network derivative attributes.
All the data is open and non-proprietary. However, users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. This dataset is not intended to be used for site-specific regulatory determinations.
3DHP datasets include a three-dimensional (3D) hydrography network generated from, and integrated with, elevation data from the 3DEP to better represent stream gradients and channel conditions, along with waterbodies, hydrologic units, hydrologically enhanced elevation and other surfaces, and more consistent and accurate attributes.
This product is new in Federal Fiscal Year 2026 (FY26), and consists only of vector data in a series of feature classes. The product represents the 3DHP dataset and the schema in which it is contained as of September 30, 2025. Future Annual Staged Product releases will reflect the schema at the time the product is generated and include more EDH-sourced data holdings.

title: Subnational Methane Monitor

description: Methane, a greenhouse gas 80 times more potent than CO2 in the near term, drives nearly one-third of current warming. Yet it remains under-addressed in many climate strategies. To stay on track for 1.5 °C, we must slash methane emissions quickly, especially from energy, agriculture, and waste.

 

While national pledges set the stage, subnational governments and local stakeholders implement the day-to-day policies and projects that move the needle. Cities, states, provinces, and regions are in the position to experiment with tailored regulations and pilot initiatives. However, there is currently a lack of integrated tracking of subnational emissions and actions, which hinders transparency and the exchange of successes and lessons learned.

 

To fill a critical information gap, the California-China Climate Institute (CCCI) proudly launches the Subnational Methane Monitor—the first centralized, global platform tracking:

 





Policies: Local regulations, targets, and binding standards across sectors




Projects: Pilot and scaled-up efforts in waste management, dairy digesters, pipeline leak detection, and more




Emissions: Time-series data and trend visualizations at subnational resolution



 

The current version includes subnationals in the United States and China. By aggregating data on regulations, evaluating policy ambition, mapping pilot projects, and visualizing emission trends, this platform empowers jurisdictions to identify gaps, benchmark progress, and share best practices. Bridging the gap between local action and global climate goals, the Subnational Methane Monitor turns data into actionable insights, accelerating collaboration to curb this super-pollutant.
