Last news:
The GhoSST service contains:
An experimental database on "spectroscopy of solids" of planetary and astrophysical interests. It covers different types of natural and synthetic solid samples (molecular solids / ices, minerals and rocks, organics and carbonaceous materials, meteorites, ...) measured with various spectroscopic techniques from the VUV to the mm ranges (transmission, reflectance, Raman and Fluorescence emissions, microscopy, ...) and providing their spectra, as well as a list of their absorption bands (molecular solids only).
This solid spectroscopic database provides to the community various sets of laboratory data necessary for the analysis of the numerous spectroscopic observations of surfaces, atmospheric aerosols and grains of the solar system objects (planets, satellites, asteroids, comets, TNO, ...), and of interstellar and circum-stellar grains generated by the planetary space missions, space-born observatories and ground-based telescopes. It will be also of strong use by scientists performing laboratory experiments on solids samples or analyzing samples of extraterrestrial matter. Part of these data will be also useful for many terrestrial studies (glaciology and snow studies, aerosols, geology, etc.).
This database is online since September 25th 2012 and in the process of data ingestion.
A database on the "physical properties molecular solids" based on bibliographical reviews and critical analyses of published data (measurements, theoretical calculations ...) completed by our own measurements and computations. It should to allow astrophysicists, planetary scientists and geophysicists to model the various physical processes of the universe involving molecules in the condensed state and their exchanges with the gas phase. The development of this database still needs to be funded.
The spectroscopic database of GhoSST provides experimental data and products from IPAG on:
The database still contain only a small number of these spectroscopic data compared to the selection of the best data accumulated during the last 20 years of spectroscopic experiments at LGGE-LPG-IPAG: > 2000 spectra and spectral products for > 120 synthetic and natural materials in various solid states and temperatures (out of > 25000 recorded spectra).
The data feeding of the database with only fully validated data is in progress. But it is a tremendous and long term work! It will strongly depend on the scientific manpower devoted to this service in the coming years for data analysis, validation, and documentation. But 2012-2013 should be quite productive!
GhoSST (v0.5, beta version) has been opened to the public on September 25th 2012. GhoSST v0.6 (including datamodel and software features updates) has been released on February 4th 2014.

The current GhoSST web interface provides users with a number of tools for searching, displaying and exporting spectra:
Login (registration) is not necessary for search and display of spectra but only to access detailed information and for data export.
This beta version, under stabilization phase, may still contain some bugs. Please report them through the ‘contact’ form (at bottom of page)
The GhoSST database capabilities and tools will continue to evolve. The main developments in progress are:
