HyperLeda

Leda

Subject(s)
Content type(s)
Country
HyperLeda is an information system for astronomy: It consists in a database and tools to process that data according to the user's requirements. The scientific goal which motivates the development of HyperLeda is the study of the physics and evolution of galaxies. LEDA was created more than 20 years ago, in 1983, and became HyperLeda after the merging with Hypercat in 2000

SSHADE

Solid Spectroscopy Hosting Architecture of Databases and Expertise

Subject(s)
Content type(s)
Country
SSHADE is an interoperable Solid Spectroscopy database infrastructure (www.sshade.eu) providing spectral and photometric data obtained by various spectroscopic techniques over the whole electromagnetic spectrum from gamma to radio wavelengths, through X, UV, Vis, IR, and mm ranges. The measured samples include ices, minerals, rocks, organic and carbonaceous materials... and also liquids. They are either synthesized in the laboratory, natural terrestrial analogs collected or measured in the field, or extraterrestrial samples collected on Earth or on planetary bodies: (micro-)meteorites, IDPs, lunar soils... SSHADE contains a set of specialized databases from various research groups, mostly from Europe. It is developed under the H2020 European programs* "Europlanet 2020 RI" and now "Europlanet 2024 RI" with the help of OSUG, CNRS/INSU, IPAG, and CNES. It is hosted by the OSUG data center / Université Grenoble Alpes, France. It can also be searched through the Virtual European Solar and Planetary Access (VESPA) virtual observatory.

The Infrared Space Observatory data archive

ISO Data Archive

Subject(s)
Content type(s)
Country
The Infrared Space Observatory (ISO) is designed to provide detailed infrared properties of selected Galactic and extragalactic sources. The sensitivity of the telescopic system is about one thousand times superior to that of the Infrared Astronomical Satellite (IRAS), since the ISO telescope enables integration of infrared flux from a source for several hours. Density waves in the interstellar medium, its role in star formation, the giant planets, asteroids, and comets of the solar system are among the objects of investigation. ISO was operated as an observatory with the majority of its observing time being distributed to the general astronomical community. One of the consequences of this is that the data set is not homogeneous, as would be expected from a survey. The observational data underwent sophisticated data processing, including validation and accuracy analysis. In total, the ISO Data Archive contains about 30,000 standard observations, 120,000 parallel, serendipity and calibration observations and 17,000 engineering measurements. In addition to the observational data products, the archive also contains satellite data, documentation, data of historic aspects and externally derived products, for a total of more than 400 GBytes stored on magnetic disks. The ISO Data Archive is constantly being improved both in contents and functionality throughout the Active Archive Phase, ending in December 2006.

AVISO+

Satellite Altimetry Data

Subject(s)
Content type(s)
Country
AVISO stands for "Archiving, Validation and Interpretation of Satellite Oceanographic data". Here, you will find data, articles, news and tools to help you discover or improve your skills in the altimetry domain through four key themes: ocean, coast, hydrology and ice. Altimetry is a technique for measuring height. Satellite altimetry measures the time taken by a radar pulse to travel from the satellite antenna to the surface and back to the satellite receiver. Combined with precise satellite location data, altimetry measurements yield sea-surface heights.

AERONET

AErosol RObotic NETwork

Subject(s)
Content type(s)
Country
The AERONET (AErosol RObotic NETwork) program is a federation of ground-based remote sensing aerosol networks established by NASA and PHOTONS (PHOtométrie pour le Traitement Opérationnel de Normalisation Satellitaire; Univ. of Lille 1, CNES, and CNRS-INSU) and is greatly expanded by networks (e.g., RIMA, AeroSpan, AEROCAN, and CARSNET) and collaborators from national agencies, institutes, universities, individual scientists, and partners. The program provides a long-term, continuous and readily accessible public domain database of aerosol optical, microphysical and radiative properties for aerosol research and characterization, validation of satellite retrievals, and synergism with other databases. The network imposes standardization of instruments, calibration, processing and distribution.

STARK-B

Subject(s)
Content type(s)
Country
STARK-B is a database of calculated widths and shifts of isolated lines of atoms and ions due to electron and ion collisions. This database is devoted to modeling and spectroscopic diagnostics of stellar atmospheres and envelopes. In addition, it is also devoted to laboratory plasmas, laser equipments and technological plasmas. So, the domain of temperatures and densities covered by the tables is wide and depends on the ionization degree of the considered ion. The temperature can vary from several thousands for neutral atoms to several hundred thousands of Kelvin for highly charged ions. The electron or ion density can vary from 1012 (case of stellar atmospheres) to several 1019cm-3 (some white dwarfs and some laboratory plasmas).
