NIST XCOM: Photon Cross Sections Database - SRD 8
Data provided by National Institute of Standards and Technology
A web database is provided which can be used to calculate photon cross sections for scattering, photoelectric absorption and pair production, as well as total attenuation coefficients, for any element, compound or mixture (Z <= 100) at energies from 1 keV to 100 GeV. XCOM provides two forms of output: (a) tables which correspond closely in format to existing tables in the literature; (b) graphical display of the tabular data.

Almanac API - Ranking by Geography Type within the Nation
Data provided by National Telecommunications and Information Administration
This API is designed to find the rankings by any geography type within the nation with a specific census metric (population or household) and ranking metric (any of the metrics from provider, demographic, technology or speed). Support for full list of rankings by nation is not allowed for geography types (e.g., county, census place, usf) so only the top ten and bottom ten rankings would be returned through the API.

Broadband Summary API - By Geography Type and Geography ID
Data provided by National Telecommunications and Information Administration
This API returns broadband summary data by geography IDs for a specific geography type. It is designed to retrieve broadband summary data by geography and census metrics (population or households) combined as search criteria. The data includes wireline and wireless providers, different technologies and broadband speeds reported in the particular area being searched for on a scale of 0 to 1.

BTOP Map
Data provided by National Telecommunications and Information Administration
The BTOP Map allows the public to visualize the impact of more than $4 billion in broadband investments being made through the American Recovery and Reinvestment Act (Recovery Act). Organizations awarded grants through the Broadband Technology Opportunities Program (BTOP) submit performance reports that summarize their project's progress in advancing broadband access and adoption across the country. These reports can be found on the BTOP website.

NIST Thermophysical Properties of Hydrocarbon Mixtures Database- SRD 4
Data provided by National Institute of Standards and Technology
SUPERTRAPP is an interactive computer program for predicting thermodynamic and transport properties of pure fluids and fluid mixtures containing up to 20 components. The components are selected from a database of 210 components, mostly hydrocarbons. SUPERTRAPP performs phase equilibria calculations and gives the thermophysical properties of all phases and the feed.
