The Antwerp FATI is a platform to experimentally simulate the impact on ecosystems of future precipitation regimes, climate-warming and especially climate extremes such as intense droughts, flooding and heat waves (e.g. temperatures up to 10 °C above ambient). By using infrared heaters and automated rainout shelters in combination with programmable irrigation, the system can simulate such extreme events in the open air, in twelve 7 m² plots, under natural light and wind. Each plot can contain one large mesocosm unit, or many smaller ones in separate containers. In total, > 300 individual and independent experimental units can be maintained simultaneously. The automated measurements provided are: air micro-climate (air temperature, air relative humidity, incoming and outgoing radiation, wind speed, soil microclimate, canopy temperature with fixed infrared camera's that can distinguish individual containers.
