VolcPlume Portal

The VolcPlume portal is dedicated to the near-real time or retrospective tracking and analysis of the physico-chemical properties of volcanic plumes in the atmosphere, from the source to regional/global scale. The portal allows for jointly analysing a broad panel of satellite and ground-based active and passive remote sensing observations of both volcanic gas and particles, as well as in-situ ground air quality monitoring measurements to detect and isolate volcanic plume signatures down to the ground. Benefiting from developments favouring interactivity and flexibility, this portal thus aims to facilitate an in-depth assessment of the multi-scale atmospheric impacts of volcanic plumes that can include, depending on the type and magnitude of the eruption, modifications of the atmospheric chemistry, degradation of air quality, aviation hazards, and climate impacts.

A complementary feature of the VolcPlume portal allows for focusing on any active volcano in the world to determine, using remote sensing observations, temporal variations of gas and particle emissions from daily to annual timescales. Knowledge of the volcanic source, which is often highly variable with time, is indeed crucial for accurately initializing models of volcanic plume dispersion, and robustly assess atmospheric hazards. Regarding local volcanological hazards, this focus on emissions is also essential as it allows to remotely track changes in the degassing or eruptive activities of any isolated or non-instrumented volcano. In the event of a major eruption at a monitored volcano, satellite-based observations can also complement instruments deployed on the ground.

The VolcPlume interdisciplinary portal is relevant not only to the atmospheric science community but also to the earth science community, in particular volcanologists and volcanological observatories.
