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 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).
CIRAD's xylotheque is one of the most important wood collections of tropical and temperate species available to date.
