Atmospheric Forest is a large scale VR point-cloud installation that visualizes and sonifies the relations between the forest and climate. It reveals the interaction patterns between the pine-tree emissions in Pfynwald, an ancient Swiss Alpine forest, and weather conditions in this valley, effected by drought. The trees do not only produce oxygen, but they are living bodies who breath too. I.e., they emit part of carbon dioxide, sometimes even up to 20 perc. from what they have consumed. When trees die, they release all the carbon they have collected during their lives back into the atmosphere. Atmospheric Forest explores the effects of drought on local forest ecosystems, and how such stress situations influence production of resin and volatile emissions (such as usual pine-tree scent).
