This project, located at the USDA/ARS facility in Temple, TX, is the first field project to provide a continuous gradient of atmospheric CO2. The grassland system has been operating since the spring of 1997, manipulating CO2 concentrations from 200 to 550 ppm (concentrations found at the end of the last ice age to those reached sometime next century). Funding for the research comes from the USDA/ARS (the global change group of Polley, Johnson, and Torbert), the Texas Agricultural Experiment Station (Dugas), and NIGEC/DOE (Jackson).
