EUREF Permanent Network

EPN

Subject(s)
Content type(s)
Country
The EPN (or EUREF Permanent Network) is a voluntary organization of several European agencies and universities that pool resources and permanent GNSS station data to generate precise GNSS products. The EPN has been created under the umbrella of the International Association Geodesy and more precisely by its sub-commission EUREF. The European Terrestrial Reference System 89 (ETRS89) is used as the standard precise GPS coordinate system throughout Europe. Supported by EuroGeographics and endorsed by the EU, this reference system forms the backbone for all geographic and geodynamic projects on the European territory both on a national as on an international level.

biodiversity.aq

ANTABIF dataportal

Subject(s)
Content type(s)
Country
Antarctic marine and terrestrial biodiversity data is widely scattered, patchy and often not readily accessible. In many cases the data is in danger of being irretrievably lost. Biodiversity.aq establishes and supports a distributed system of interoperable databases, giving easy access through a single internet portal to a set of resources relevant to research, conservation and management pertaining to Antarctic biodiversity. biodiversity.aq provides access to both marine and terrestrial Antarctic biodiversity data.

The following databases are maintained at IAA-ULB: Nuclear Database (BRUSLIB - A collection of nuclear data (masses, fission barriers, E1 strength functions, nuclear level densities, partition functions, reaction rates) of interest for nuclear astrophysics, stellar evolution and nucleosynthesis), Nuclear Network Generator NetGen (A tool for generating nuclear-reaction rates on user-defined networks), NACRE II (An update of the Nuclear Astrophysics Compilation of Reaction Rates (NACRE) including the evaluation of 34 reactions on stable targets with mass numbers A<16), The Ninth Catalogue of Orbits of Spectroscopic Binaries (SB9), The Henize sample of S stars, The radial-velocity monitoring of barium and S stars, Molecular linelist (Molecular linelists for stellar spectra), and Stellar models (Pre-main-sequence and super-AGB phases).

The Atomic Line List

The Atomic Line List v2.04

Subject(s)
Content type(s)
Country
This is a compilation of approximately 923,000 allowed, intercombination and forbidden atomic transitions with wavelengths in the range from 0.5 Å to 1000 µm. It's primary intention is to allow the identification of observed atomic absorption or emission features. The wavelengths in this list are all calculated from the difference between the energy of the upper and lower level of the transition. No attempt has been made to include observed wavelengths. Most of the atomic energy level data have been taken from the Atomic Spectra Database provided by the National Institute of Standards and Technology (NIST).

Subject(s)
Content type(s)
Country
EM-DAT is a global database on natural and technological disasters, containing essential core data on the occurrence and effects of more than 22,000 disasters in the world, from 1900 to present. EM-DAT provides geographical, temporal, human and economic information on disasters at the country level. The database is compiled from various sources, including UN agencies, non-governmental organisations, insurance companies, research institutes and press agencies.
