CHIANTI

An Atomic Database for Spectroscopic Diagnostics of Astrophysical Plasmas

Subject(s)
Content type(s)
Country
CHIANTI consists of a critically evaluated set of up-to-date atomic data, together with user-friendly programs written in Interactive Data Language (IDL) and Python to calculate the spectra from astrophysical plasmas.

X-Ray Database

X-ray interactions with matter

Subject(s)
Content type(s)
Country
The primary interaction of low-energy x rays within matter, viz. photoabsorption and coherent scattering, have been described for photon energies outside the absorption threshold regions. These tables are based on a compilation of the available experimental measurements and theoretical calculations. For many elements there is little or no published data and in such cases it was necessary to rely on theoretical calculations and interpolations across Z. In order to improve the accuracy in the future considerably more experimental measurements are needed.

The NIST Reference on Constants, Units, and Uncertainty

Values of Fundamental Physical Constants

Subject(s)
Content type(s)
Country
This database gives values of the basic constants and conversion factors of physics and chemistry resulting from the 2002 least-squares adjustment of the fundamental physical constants as published by the CODATA Task Group on Fundamental Constants and recommended for international use by CODATA.

Earthdata powered by EOSDIS

Earth Observing System Data and Information System

Subject(s)
Content type(s)
Country
Earthdata powered by EOSDIS (Earth Observing System Data and Information System) is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources – satellites, aircraft, field measurements, and various other programs. EOSDIS uses the metadata and service discovery tool Earthdata Search https://search.earthdata.nasa.gov/search. The capabilities of EOSDIS constituting the EOSDIS Science Operations are managed by NASA's Earth Science Data and Information System (ESDIS) Project. The capabilities include: generation of higher level (Level 1-4) science data products for several satellite missions; archiving and distribution of data products from Earth observation satellite missions, as well as aircraft and field measurement campaigns. The EOSDIS science operations are performed within a distributed system of many interconnected nodes - Science Investigator-led Processing Systems (SIPS), and distributed, discipline-specific, Earth science Distributed Active Archive Centers (DAACs) with specific responsibilities for production, archiving, and distribution of Earth science data products. The DAACs serve a large and diverse user community by providing capabilities to search and access science data products and specialized services.

Pedestrian Dynamics Data Archive

Data archive of experimental data from studies about pedestrian dynamics

Subject(s)
Content type(s)
Country
This data archive of experiments studying the dynamics of pedestrians is build up by the Institute for Advanced Simulation 7: Civil Safety Research of Forschungszentrum Jülich. The landing page provides our own data of experiments. Data of research colleagues are listed within the data archive at https://ped.fz-juelich.de/extda For most of the experiments, the video recordings, as well as the resulting trajectories of single pedestrians, are available. The experiments were performed under laboratory conditions to focus on the influence of a single variable. You are very welcome to use our data for further research, as long as you name the source of the data. If you have further questions feel free to contact Maik Boltes.

Content type(s)
Country
The CERN Open Data portal is the access point to a growing range of data produced through the research performed at CERN. It disseminates the preserved output from various research activities, including accompanying software and documentation which is needed to understand and analyze the data being shared.

National Mine Map Repository

NMMR

Subject(s)
Content type(s)
Country
The National Mine Map Repository (NMMR) collects, maintains, and provides U.S. coal and non-coal mine maps to individuals, public and private sectors. NMMR mine maps and data are searchable and indexed by state, county, company name, and mine name. Accessing NMMR mine maps and data requires contacting NMMR. NMMR has a diverse customer population and has provided data to efforts supporting industrial and commercial development, highway construction, and the preservation of public health, safety and welfare.
