Physiological assessment of whole-tree response to an extreme heatwave

The twelve Whole Tree Chambers at Western Sydney University's Hawkesbury Institute for the Environment provide fully enclosed, controlled environments for trees up to nine metres tall. In these chambers, researchers can manipulate the environment around a tree; including air temperature, soil moisture, irrigation, CO2 levels and humidity to predict the integrated effects of altered climates on tree physiology. In this experiment, Whole-tree chambers were used to expose Eucalyptus parramattensis trees to an extreme 4-day heatwave. This package of data contains CO2 and H2O exchange rates between whole-tree crowns and the atmosphere, environmental data including temperature, humidity, and light, continuous measurements of canopy temperature, assessments of leaf and branch hydraulic status, measurements of leaf thermal tolerance, and biometric measurements of tree size
