The Program for Experimental Atmospheres and Climate (Péac: which means ‘to sprout’ in Irish) is a new state-of-the-art plant growth room facility funded by Marie Curie, UCD College of Life Sciences and UCD School of Biology and Environmental Science.
The facility comprises a suite of eight CONVIRON BDW40 walk-in plant growth rooms with full monitoring and control of climatic and atmospheric conditions. Each chamber which measures 3.7m2 in area and 2.4m in height can concurrently control atmospheric CO2 (380 to 2000 ppmV), O2 (9 to 21%) and SO2 (200 to 2000 ppbV) to within 10ppmV, 0.1% and 100 ppb respectively of set point. Chamber temperature (-5 to 40ºC), relative humidity (35 to 90%), light intensity (300 to 1100 μmol) and photoperiod are also all tightly controlled to set point conditions.
The Péac facility enables researchers within the UCD Plant Palaeoecology and Paleobiology group to undertake both long-term and short-term investigation of the ecophysiological, morphological and anatomical responses to any simulated past or future climatic and/or atmospheric scenario under rigorously controlled experimental conditions.
