Eurochamp Data Center

Simulation chamber data and data products

The EUROCHAMP Data Centre provides scientists with free and open access to data from simulation chamber experiments as well as mature products and tools that support activities related to atmospheric observations and modelling. These data, products and tools are supplied by EUROCHAMP-2020 as well as EUROCHAMP-1 and -2 partners. This Data Centre gives access to three databases:

  • The Database of Atmospheric Simulation Chamber Studies (DASCS): This database provides a compilation of experimental and modelled data obtained from experiments in simulation chambers supplied by all partners of the consortium. These experiments can be used to further understanding of the atmospheric processes involved in air pollution and climate change, as well as their impact on health and cultural heritage. These data are highly useful for the development and the validation of atmospheric models.
  • The Library of Analytical Resources (LAR): This database provides infrared, UV and mass spectra of atmospheric key species as well as mass spectra of derivatives at mid to high resolutions. Most of the spectra are calibrated to allow for quantification of species. The specificity of this library is that it focuses on atmospheric species and provides spectra of complex molecules which cannot be found elsewhere, some of them being synthesized as they are not commercially available.
  • The Library of Advanced Data Products (LADP): This database will provide different types of mature and high level products of chamber experiments which are especially useful for researchers working on atmospheric observations, as well as atmospheric model development and validation. It includes products for the development of chemical mechanisms in atmospheric models (e.g. rate coefficients, photolysis frequencies, SOA yields, vapor pressures, etc.), products for the retrieval of satellite data and for radiative transfer modelling (e.g. mass extinction coefficients of aerosols, hygroscopic properties of aerosols), and tools to generate oxidation schemes which are very useful to interpret field measurements as well as laboratory studies. This database will be available in 2018.
