The Terestrial Ecophysiological Research Area (TERA) is a facility being used to examine the effects of elevated CO[sub 2] and global climate change on Douglas fir (Pseudotsuga menziesii (Mirb) Franco) seedlings. TERA consists of 12 climate-controlled growth chambers (Terracosms) that are illuminated with natural sunlight. Terracosm environmental conditions continuously mimic diurnal and seasonal changes in ambient air temperature, dew point temperature, and CO[sub 2] concentration to [+-] 1.5[degrees]C, [+-] 5[degrees]C, and [+-] 20 ppm, respectively. The terracosms are extensively instrumented in order to examine above- and belowground processes. All sensors, analytical instruments, and data acquisition equipment required for independent operation are located at each Terracosm. Data quality control is insured with centralized, redundant instrumentation. The TERA research facility will be described, including overall system performance and terracosm climate control.
