The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. The ACS covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population. Summary files include the following geographies: nation, all states (including DC and Puerto Rico), all metropolitan areas, all congressional districts (117th Congress), all counties, all places, and all tracts and block groups.

These four data files contain datasets from an interlaboratory comparison that characterized a polydisperse five-population bead dispersion in water. A more detailed version of this description is available in the ReadMe file (PdP-ILC_datasets_ReadMe_v1.txt), which also includes definitions of abbreviations used in the data files. Paired samples were evaluated, so the datasets are organized as pairs associated with a randomly assigned laboratory number.

Here we provide curated analytical chemistry data for eggs collected from 1999 to 2010 on a subset of species and analytes that were measured regularly and reasonably systematically. Included in this publication are 487 samples analyzed for 174 ubiquitous environmental contaminants such as (poly)brominated diphenyl ethers (BDEs), mercury, organochlorine pesticides (OCPs), and polychlorinated biphenyls (PCBs). Data were collated to form a dataset useful in chemometric and related analyses of the marine ecosystem in the north Pacific Ocean.

NIST collects and reports numerous metrics semiannually to the White House Office of Science and Technology Policy to demonstrate implementation of the NIST Plan for Public Access. These metrics include: the number of NIST data management plans (internal and external); the number of datasets listed on data.gov and made public on NIST's website; datasets accessed through NIST's data discovery tool; publications available through PubMed Central (PMC) and govinfo; and publications accessed through PMC.

Data collected includes results for a transmit volume optimization (TVO) method utilized in audio device characterization. Optimal transmit volume of Land Mobile Radios (LMR) including direct mode operation (P25 and analog) and trunked mode operation (P25 trunked Phase 2). Final Data is included as .csv and raw .mat files, as well as transmit audio files to be used for testing.
