Biogenic emission estimates for 1995

Biogenic emissions during 1995 for the contiguous United States have been estimated with the Biogenic Emissions Inventory System (BEIS2.2). Hourly emissions were computed for each county using surface observations from the National Weather Service and land use data developed specifically for biogenic emission calculations. Meteorological data were interpolated to each county with Barnes analysis. The occurrence of the first and last date of freezing, as interpolated using Barnes analysis, was used to toggle the occurrence of deciduous leaf biomass. The estimates indicate annual emissions of 17.2 million metric tons (Tg) of isoprene, 6.1 Tg of monoterpenes, 6.5 Tg of other volatile organic compounds, and 1.4 Tg of nitric oxides. These estimates are reasonably consistent with those made by other researchers and are slightly lower than estimates for 1990 made with an earlier version of BEIS2. The slight decrease in estimated 1995 emissions compared to 1990 can be attributed to the use of freezing dates, better temporal resolution of data (hourly values versus monthly diurnal averages), and year-to-year variations in meteorology.
