Volatile organic compound and nitric oxide emissions from corn in the midwestern United States. Interim report, October 1991-October 1992
Biogenic emissions are needed for photochemical oxidant modeling. The current biogenic emissions inventory assumes rather high volatile organic compound (VOC) and low nitric oxide (NO) emissions from corn. The high VOC emission flux assumed for corn has not been substantiated by recent field measurements. In contrast, some field measurements have suggested that biogenic NO emissions from heavily-fertilized fields may be significant, greater than 10% of the total NOx budget in the midwestern United States. These uncertainties in biogenic emission factors for corn deserve attention, because of the large acreage of corn that grows upwind of the urban ozone nonattainment areas around Lake Michigan. The paper compares anthropogenic emissions of NOx and VOC with biogenic emission estimates. Emission factors for corn are varied by assuming a lower and an upper-bound for both VOC and NO. Temporal and spatial variations in these estimates are examined for a three-day period in July 1988.
