February 5, 2008 Dean Vickers provided CDIAC with three files (cyp00.asc, cyp01.asc, and cyp02.asc) containing half-hourly CO2 storage estimates and mean CO2 concentrations for the old or first Metolius young ponderosa pine site (US-Me5). The CO2 concentrations in these new files replace the CO2 concentrations previously furnished in the files yp00.asc, yp01.asc, and yp02.asc.
