MATS Modeling Results

Introduction

MATS Configuration

  • MATS version 2.6.1
  • 5-year weighted average (2009-2011, 2010-2012, 2011-2013)
  • Maximum concentration in a 3x3 array of model grid cells
  • Inverse around the monitor using inverse distance weighting
  • No spatial gradient adjustment
  • A site needs to have a concentration of at least 60 ppb for 5 or more days in the year to be plotted

The first set of results shows the base year (CAMx 2011a) and future year (Base2020a_11) design values and relative reduction factors (RRF=future DV/base DV). The future year DV and RRF plots show fewer sites than the base year DV plot because in the future year several sites fall below the 60 ppb minimum threshold concentration.

These next plots show the same thing as the previous plots except the scales have been adjusted to show all sites in the domain. The sites that fall below the 60 ppb threshold are now shown in grey.

The plots below compare the Base2011a and Base2011a2 DVs. The RRF plot on the right shows the ratio of Base2011a2/Base2011a
