The downside to good air.

• There are no episodes to diagnose or symptoms to
  indicate that there is a problem.
• Emissions inventories and pollution models cannot
  be validated.

FAQS Air Quality Modeling Grids (36km,12km,4km)

• Met grid, 36km 48x66, 12km54x60, 4km 81x105

Initial Simulation August 11-20, 2000

• MM5v3 ran with Eta data and 4DDA and Land Surface
  Model Options
• MM5v3 run with two-way nested 108km and 36km
  grids, but 12km and 4km run one way
• SMOKE ran with projected FAQS_2000 inventory, old
  census data including old urban definitions
• CMAQ currently ran with SAPRC99 , without PinG
• Projection Map Lambert Conformal, 30,60,-90.
  Vertical sigma-p.
• CMAQ grid 3 cells less than MM5 grid at every
  border, now CMAQ only run with 12 km and 4 km
  grids

Initial Results and First Evaluation

• 24 Ozone Sites in Georgia, 21 of them located in
  both 12km and 4km grids
• Evaluation will be with O3, NOx, CO, PAN, VOCs,
  currently only O3
• 22 Meteorological sites in 12 km grid, 3 of them
  have sounding data, 21 of them have data during
  the episode, used for 12 km grid site vs. site
  evaluation
• Meteorology evaluated with surface winds (10
  meters), air temperature (2 meters), humidity,
  pressure.
• Modeled data has been corrected to the same
  height as measured data, coming with mixing
  depth, precipitation
• One of the evaluation objectives is to look at
  the useful information for improving the emission
  inventory

Year 2 Progress Report

• FAQS is on schedule for completion 12/03.
• Budget work-arounds are holding sufficiently
  well.
• Monitoring network is stable and fully
  operational.
• Initial emission inventories and modeling show
  progress, but require significant improvements.
• WE NEED EPISODES IN SUMMER 2002!
