Observation system within France’s National Service for Volcanological Observation (SNOV).The system contributes complete, integrated, data sets for eruptive products from : field studies (i.e., field mapping, outcrop and sample descriptions), textural analysis (i.e., particle size and size distribution, morphology, density, porosity, connectivity, permeability and vesicle and crystal size, distribution, shape and orientation),and chemical data (i.e., bulk and glass chemistry).
This observation system deals with the monitoring of the biological, microphysical and chemical properties of clouds. The aqueous phase of clouds is collected at the Puy de Dôme observatory using the cloud impactors developed at LaMP/OPGC. Biological and chemical analyses are performed in collaboration with the ICCF (Université Clermont Auvergne).
Observation system for quantitative and qualitative parameters measurements of the water masses characteristic in Auvergne in order to observe the long-term evolution of the hydrosystems according to the anthropic and climatic modifications.
