Advection Visualized

Georg spent a week in Aosta Valley, Italy, studying CO2 advection at the subalpine grassland site Torgnon together with Marta Galvagno and colleagues from ARPA Valle d’Aosta. The pictures show the study site in the fading light of day and the prominent peak of Matterhorn (Cervino) across the border to Switzerland. The video shows an attempt to visualise nighttime downslope flows using a fog machine (usually used for parties ….).
