Table A6b: Summary of average meteorological quantities and air pollutant concentrations (and ratios) measured at OLC for all individual Fort Benning burn days in March 2003, separated by the morning pre-burn conditions, the afternoon flaming stage (yellow), the evening smoldering stage (orange), and the nocturnal post- burn (purple), and potential plume impact stages (grey). All data for periods with easterly component winds, hence potential direct emissions impact, are bold. Acres burned and direction of burn unit relative to OLC are in italic.
