FACE
in scheme: projects
definition: FACE provides a technology by which the microclimate around growing plants may be modified to simulate climate change conditions. Typically CO2-enriched air is released from a circle of vertical pipes into plots up to 30m in diameter, and as tall as 20 m. Measurements of photosynthesis and carbon sequestration under present conditions do not reveal how these processes will behave in the CO2-enriched atmosphere of the future. FACE creates realistic, mid-21st century CO2 conditions in which processes regulating plant and ecosystem responses to future conditions are quantified. FACE technology now has a long track record of operating efficiently and cost effectively for a broad range of ecosystems providing a research platform for many hundreds of investigators.
