e/Free-air concentration enrichment

Information
has gloss	eng: Free-Air Carbon dioxide Enrichment (FACE) is a method used by ecologists and plant biologists that raises the concentration of in a specified area and allows the response of plant growth to be measured. Experiments using FACE are required because most studies looking at the effect of elevated concentrations have been conducted in labs and where there are often factors other than concentration that affect growth, for example the pot effect. Measuring the effect of elevated using FACE is a better way of estimating how plant growth will change in the future as the concentration rises in the atmosphere due to man-made emissions. FACE also allows the effect of elevated on plants that cannot be grown in small spaces (trees for example) to be measured.

Meaning
German
has gloss	deu: Free Air Carbon Dioxide Enrichment oder kurz FACE ist eine technische Versuchsanordnung, die es ermöglicht, die steigende Kohlendioxid-Konzentration (Hauptursache der Globalen Erwärmung) im Freiland zu simulieren und ihren Einfluss auf Pflanzen und Ökosysteme zu untersuchen. Bis 2006 gab es 32 FACE-Anlagen weltweit, die sich zu gleichen Teilen auf natürliche und künstliche Ökosysteme verteilten.
