2020 Planning Database - State and County Level

Data provided by  United States Census Bureau

This is a one-time release of the Census Bureau’s Planning Database (PDB). This version of the PDB is at the state and county levels of geography. It contains only select U.S. housing, demographic, and socioeconomic statistics from the 2010 Census and the American Community Survey, not the operational statistics found on most versions. This special release of the PDB can be easily combined with county and state level statistics from other data sources.

Time Series Data from Sensors in the Duct Above a Kitchen Cooktop During Normal Cooking and Ignition Conditions

Data provided by  National Institute of Standards and Technology

This data set includes the time series data from 16 electrochemical, optical, temperature and humidity sensors in 60 experiments to characterize the conditions preceding cooktop ignition compared to the conditions of normal cooking. The sensors are placed in the exhaust duct above a mock-up kitchen cooktop. Experiments cover a broad range of conditions, including both unattended cooking and normal cooking scenarios, where 39 experiments led to auto-ignition.

pySCATMECH: A Python interface to the SCATMECH C++ library of polarized light scattering codes

Data provided by  National Institute of Standards and Technology

SCATMECH is a library of object-oriented C++ computer codes originally developed for disseminating models for polarized light scattering from surfaces and aerosols and for diffraction from gratings. The pySCATMECH package has been developed as an interface to the SCATMECH library, simplifying use of the codes and allowing for more rapid development of software for these applications.

Atom-Based Device Navigator (ABDNavigator)

Data provided by  National Institute of Standards and Technology

ABDNavigator is software written for scanning probe (e.g. scanning tunneling microscope) control and sample navigation of atom-based devices. Here atom-based devices refer to devices whose components span from the micron scale range down to sub nanometer and are probed, and typically fabricated by scanning tunneling microscope.

Tool for Evaluation of Vaporized Hydrogen Peroxide Disinfection of N95 Masks in Rooms

Data provided by  National Institute of Standards and Technology

The SARS-CoV-2 virus has put a strain on the supply and distribution of N95 masks, with some hospitals electing to reuse masks after disinfection. Currently, vaporized hydrogen peroxide (VHP) mask disinfection systems are being deployed at multiple locations throughout the United States, for example in shipping containers and in small rooms. Such enclosures will be of a different size, have different surface materials and have varying air change rates; all these parameters will impact the VHP dose that the masks receive.

Data for "Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability"

Data provided by  National Institute of Standards and Technology

This data was used for main results for the paper entitled "Coherent Optical Clock Down-Conversion for Microwave Frequencies with 10-18 Instability".
We could calculate relative phase fluctuation and Allan deviation for both Yb optical clocks and 10 GHz microwaves. Uncertainty of our down-conversion system was also calculated from this.

2014-2018 American Community Survey: Migration Flows

Data provided by  United States Census Bureau

Migration flows are derived from the relationship between the location of current residence in the American Community Survey (ACS) sample and the responses given to the migration question "Where did you live 1 year ago?". There are flow statistics between state or world region of residence 1 year ago and current county of residence. In addition to the flow estimates, there are supplemental statistics files that contain migration/geographical mobility estimates (e.g. nonmovers, moved to a different state, moved from abroad) for each current residence county.
