SMOKE 2008b emissions results

Introduction

The 3SAQS used the Sparse Matrix Operator Kernel Emissions (SMOKE) processing system version 3.5.1 to prepare emissions inputs for photochemical grid models (PGMs). The 3SAQS 2008 emissions modeling platform consists of data and software to estimate air emissions fluxes that best represent the conditions in the 3SAQS modeling domain during 2008. The base 2008 modeling period is annual, and included a model spin-up period from December 16 to December 31, 2008. The modeling domain includes a 36 km continental US (CONUS) domain with a 12 km nest over the western U.S.

The following sectors were used to represent air pollutant emissions for the 3SAQS:

  • Aircraft/locomotive/marine (ALM)
  • Off-road mobile (Nonroad)
  • On-road mobile (Onroad)
  • Non-point/Area (Nonpoint)
  • Fugitive Dust
  • Fertilizer
  • Livestock
  • Residential Wood Combustion (RWC)
  • Area oil and gas (Area O&G)
  • Point oil and gas (Point O&G)
  • Continuous Emission Monitor (CEM) point (EGU Point)
  • Non-CEM point (NonEGU Point)
  • Offshore shipping (Offshore)
  • Fires (Fire)
  • Canada and Mexico sources (Non-US)
  • MEGAN biogenics (Biogenic)
  • Windblown dust (WBD)
  • Sea salt
  • Lightning

Details of the sources and nature of these emissions data are provided in the 3SAQS 2008 Modeling Protocol.
