Abstract A fully automated system measuring C2–C6 hydrocarbon concentrations and vertical gradients was installed at Harvard Forest in Petersham, Massachusetts, using a gas chromatograph with dual flame ionization detectors and cryogenic sample preconcentration. Measurements were made simultaneously at two heights above the forest canopy at forty five minute intervals, continuously from July 1992 to the present. Data for concentration gradients were combined with CO2 flux measured by eddy correlation to determine the rates of production of biogenic hydrocarbons by the forest.
