Abstract
This report describes the methodology used to develop a natural hydrocarbon emission inventory for the Tampa/St. Petersburg Florida area. Hydrocarbon emissions for more than 600 vegetation samples were collected and quantified chromatographically in terms of Total Nonmethane Hydrocarbons, Paraffins, Olefins, Aromatics, and Methane. The report also includes a detailed study of vegetation type, amount, and distribution over the study area. Hourly emission factors were determined for each hydrocarbon component and species. These emission factors are coded onto a 1.5 x 1.5 km grid measuring 54 x 40 which covers the study area. Emission rates for various Florida vegetation species, associations, and land use categories are given. The principal investigator calculates that natural emissions during the summer months are approximately 160 metric tons per day, or an average emission flux of approximately 1350 microgram/sq m/hr during the daytime (30 C) and 700 microgram/sq m/hr during the nighttime (25 C). Isoprene, the single largest nonmethane emission component, is approximately 18% of the daily TNMHC emission. The next largest emission component is a-Pinene (10% of daily TNMHC emission). Methane emissions were calculated to be approximately 33% of the TNMHC plus methane total. The data is recorded on computer tape which contains all field data, the emission factors, and the computer programs used to generate the hydrocarbon emission inventory.
