The DYNVOLC Observation Service provides complete and integrated data sets for eruptive products from: field studies (ie, field mapping, outcrop and sample descriptions), texture analysis (ie particle size distribution, morphology, density, porosity, connectivity, permeability and vesicularity, and size, shape, distribution and orientation of crystals), and chemical data

The GAZVOLC observation service provides databases on volcanic gas emissions.

The study of magma degassing and hydrothermal systems is of the utmost importance to deepen our understanding of the dangers that these systems present, and to optimize their monitoring. Since the rate of rise of gases towards the surface is much greater than that of magma, any change in the composition or flow of magmatic gases and / or volcanic fluids at the surface provides information on what is going on in depth (interactions chemicals between volcanic gases, surrounding rocks and rainwater, or the arrival in depth of new inputs of magma and gas).

HOTVOLC is a service based on the use of satellite data and dedicated to real-time observation of volcanic products. This application uses automated data ingestion from MSG-SEVIRI geostationary satellites.

This allows the acquisition of High Rate Information Transmission (HRIT) format images, corresponding to the corrected data, and undesirable radiometric and geometric effects. The images are geolocated, calibrated and linearized.

HRIT digital counts are converted to spectral radiance and then processed using a validated algorithm for automatic distribution of ready-to-use products on a complete WEB-GIS interface.

This Lidar configured for eye safety was acquired at the beginning of 2008. It allows the tracking of aerosol layers and fine clouds in the troposphere. It is equipped with polarized channels and a RAMAN nitrogen channel to determine the abundance and shape of the particles. Soon equipped with a RAMAN steam path, it will also be possible to study the profiles of atmospheric water vapor.

This observation service deals with the monitoring of the biological, microphysical and chemical properties of clouds. The aqueous phase of the clouds is collected at the Puy de Dôme observatory using cloud impingers developed at LaMP / OPGC. The biological and chemical analyzes are carried out in collaboration with the ICCF (Clermont Auvergne University).

The Auvergne Seismological network is composed of 21 stations which are intended for the general sisimic surveillance of the territory: real-time monitoring of seismicity, determination of the source parameters of earthquakes in the French territory and archiving of seismograms for research purposes.

VOLDORADs (VOLcano DOppler RAdar) are portable volcanological Doppler radars designed at OPGC specifically for the study and monitoring of explosive volcanic eruptions.

Adapted from wind profiling UHF radars, they represent a state-of-the-art remote sensing tool in the study and monitoring of lava streams and ash plumes, where the dominant reflectors are the lava particles propelled above the vent by the violent expansion of magmatic gases under pressure.

The Airborne Measurements Platform (AMP) is a suite of scientific instruments used to characterize the microphysical and optical properties of cloud particles in situ. It is on board research aircraft, such as those of the French SAFIRE fleet for example, during airborne measurement campaigns. The AMP has been labeled "National Instrument" by the INSU since 2008. As such, it is made available to the entire national scientific community. The data collected during campaigns is also made available to the community, depending on the projects and the applicable internal data management policy.
