The document is a user's guide for an updated Personal Computer version of the Biogenic Emissions Inventory System (PC-BEIS2), allowing users to estimate hourly emissions of biogenic volatile organic compounds (BVOCs) and soil nitrogen oxide emissions for any county in the contiguous United States. Emission rates depend on land use, emission factors, temperature, and solar radiation. A simple canopy model is used to adjust photosynthetically active solar radiation at five vertical levels in the forest canopy. Emission rates from vegetation other than forests are expressed as BVOC carbon mass per unit land area, with a constant peak growing season biomass assumed. Light and temperature corrections are applied, but no canopy model is used for non-forested areas.
