WAQS 2011b Platform Base Year Emissions

Introduction

The WSAQS used the Sparse Matrix Operator Kernel Emissions (SMOKE) processing system version 3.5.1 to prepare emissions inputs for photochemical grid models (PGMs). The WSAQS 2011 version B (WSAQS2011b) emissions modeling platform consists of data and software to estimate air emissions fluxes that best represent the conditions in the western U.S. 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 WSAQS:

  • 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.
