The Virtual Atomic and Molecular Data Centre (VAMDC) (M.L. Dubernet et al.
2010, JQSRT 111, 2151) is an EU-FP7 e-infrastructure project devoted to
building a common electronic infrastructure for the exchange and distribution
of atomic and molecular data. It involves two dozen teams from six EU member
states (Austria, France, Germany, Italy, Sweden, United Kingdom) as well as
Russia, Serbia, and Venezuela. Within VAMDC scientists from many different
disciplines in atomic and molecular physics collaborate with users of their
data and also with scientists and engineers from the information and
communication technology community. In this presentation an overview of the
current status of VAMDC and its capabilities will be provided. In the second
part of the presentation I will focus on one of the databases which have become
part of the VAMDC platform, the Vienna Atomic Line Data Base (VALD). VALD has
developed into a well-known resource of atomic data for spectroscopy
particularly in astrophysics. A new release, VALD-3, will provide numerous
improvements over its predecessor. This particularly relates to the data
contents where new sets of atomic data for both precision spectroscopy (i.e.,
with data for observed energy levels) as well as opacity calculations (i.e.,
with data involving predicted energy levels) have been included. Data for
selected diatomic molecules have been added and a new system for data
distribution and data referencing provides for more convenience in using the
upcoming third release of VALD.Comment: 8 pages, 1 tabl
