SMOKE 2011a Emissions

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 2011 emissions modeling platform consists of data and software to estimate air emissions fluxes that best represent the conditions in the 3SAQS modeling domain during 2011. The base 2011 modeling period is annual, and included a model spin-up period from December 16 to December 31, 2011. The modeling domain includes a 36 km continental US (CONUS) domain with a 12 km nest over the western U.S. and a 4-km nest the covers the states of Colorado, Utah, and Wyoming.

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 2011 Modeling Protocol.

Results

2011 three-state total emissions, inventory sector totals, and comparisons to the other 3SAQS modeling platforms are presented here. On a state total basis Colorado has the highest 2011 emissions of CO, NOx, VOC, NH3, and methane (CH4) of the three states. Wyoming has the highest 2011 emissions of SO2 and PM species.


The following plots breakdown the emissions for each inventory pollutant by sector.
