A microprocessor controlled data acquisition system was utilized to determine the flux densities of sulfur dioxide (SO/sub 2/), carbon dioxide (CO/sub 2/), and water (H/sub 2/O) vapor above a young lob-lolly pine plantation. The average flux densities for SO/sub 2/, CO/sub 2/, and H/sub 2/O vapor for measurement periods scattered throughout the year, for this stand, were found to be 0.052 gm/sup -2/sec/sup -1/, 0.72 mgm/sup -2/sec/sup -1/, and 85 mgm/sup -2/sec/sup -1/, respectively. The experimental design, system controls, measurement techniques, control logic, and some results obtained are discussed. 11 references, 7 figures, 1 table.
