Global modeling efforts indicate semiarid regions dominate the increasing trend and interannual variation of net CO2 exchange with the atmosphere, mainly driven by water availability. Many semiarid regions are expected… More
We used eddy covariance to measure the net exchange of CO2 between the atmosphere and an old-growth tropical forest in Pará, Brazil from 1 July 2000 to 1 July 2001…. More
Methyl tertiary butyl ether (MTBE) was measured in air samples collected at hourly intervals near Blodgett Forest Research Station on the western slope of the Sierra Nevada, California, in July… More
Soil hydraulic properties at eight depths in a Fullerton cherty silt loam (a clayey, kaolinitic, thermic Typic Paleudult) profile were derived from measurements of water content with a calibrated neutron… More
Amazon forests could be globally significant sinks or sources for atmospheric carbon dioxide, but carbon balance of these forests remains poorly quantified. We surveyed 19.75 ha along four 1-km transects… More
We analyzed errors and uncertainties in time-integrated eddy correlation data for sites in the Amazon. A well-known source of potential error in eddy correlation is through possible advective losses of… More
In the southeastern United States (SE), the conversion of abandoned agricultural land to forests is the dominant feature of land-cover change. However, few attempts have been made to quantify the… More
