Status

  • Completed 2011 simulations

– CAMx & CMAQ – Both on US12 and LADCO12 domains

  • Benchmarked CAMx

– Against EPA results for 2 periods – Step by step deviation from EPA config.

  • Compared CMAQ to CAMx

Status (Cont’d)

  • Completed

performance evaluations

– Tables of statistics – Bubble plots of MNB and MNE

  • Corrected 2017

EGU emissions

– AL, GA, KY, NC, SC, TN, WV

  • Started 2017

simulations on US12

– CAMx:

  • Q1 run at 50%
  • Q234 run at 40%

– CMAQ:

  • Q1Q2 run at 20%
  • Q3Q4 run at 5%

Benchmarking

Repeat of March 22 - April 5, 2011 period with EPA configuration:

  • O3 difference
  • EC difference

Difference from EPA for the March 22-31 period: Ozone:

  • Total difference
  • Difference due to photolysis
  • Difference due to meteorology
  • Difference due to code change

EC:

  • Total difference
  • Difference due to photolysis
  • Difference due to meteorology
  • Difference due to code change

Repeat of April 21-30, 2011 period with EPA configuration:

  • Ozone difference
  • EC difference

2017 “Sensitivity” Simulations

  • 7-month ozone season on LADCO12
  • Exclude Canada/Mexico, offshore and fire

emissions from anthropogenics

  • CAMx APCA source apportionment

– Tag point EGUs in each SEMAP state (10) – Tag all other anthropogenic in each state

  • Zero-out of following emissions with CMAQ:

– Elevated EGU NOx emissions in each state – All anthropogenic NOx in each state
