1 Georgia Tech Georgia Power Environmental Engineering Fellows at (and beyond) Georgia Tech

2 Georgia Tech Objective of Georgia Power Fellowships Attract top notch graduate students to Tech Facilitate research in areas of interest to Georgia Power Educate students in areas of interest to Georgia Power for future employment Enhance communication between Georgia Power and Georgia Tech in the environmental areas

3 Georgia Tech Past and Current Fellows Katie Wade (now at Sonoma Technologies) Continuing to conduct air quality studies with health applications Diane Ivy Miranda Lowe Yu Miyashita

4 Air Quality Studies in CEE: A Sampler Armistead (Ted) Russell, Georgia Power Professor Measurement Model Development Model Application Policy / Health (www.ce.gatech.edu/~trussell) Georgia Institute of Technology Siggraph Scientific Visualization Winner Source Impacts 3-D Air quality models Sensitivity analysis Air quality measurements

5 Georgia Tech Why A Sampler? Range of Georgia Power relevant (and supported) studies a bit too much for 15 minutes… Assessment of Spatial Aerosol Composition in Atlanta (ASACA) (GP funds) Fall Line Air Quality Study (EPD + GP/SC) Roadway Study (GP +EPA funds) ARIES (NIH, EPA, EPRI, SC, GP…; with Emory) (Prof. Mulholland) Source apportionment of PM in Georgia (GP + EPA) Impact of NE Blackout (GP funds) Satellite and aircraft data assimilation (NASA) Sources of organic carbon aerosol (EPA + GP/SC) PM & ozone in the Mexico-US border region (LAUSPAU) Air quality management of regional air pollution (EPA + RFF) Climate and Air Quality (EPA) Prescribed burn impacts and management

6 Georgia Tech Why A Sampler? Range of Georgia Power relevant (and supported) studies a bit too much for 15 minutes… Assessment of Spatial Aerosol Composition in Atlanta (ASACA) (GP funds) Fall Line Air Quality Study (EPD + GP/SC) Roadway Study (GP +EPA funds) ARIES (NIH, EPA, EPRI, SC, GP…; with Emory) (Prof. Mulholland) Source apportionment of PM in Georgia (GP + EPA) Impact of NE Blackout (GP funds) Satellite and aircraft data assimilation (NASA) Sources of organic carbon aerosol (EPA + GP/SC) PM & ozone in the Mexico-US border region (LAUSPAU) Air quality management of regional air pollution (EPA + RFF) Climate and Air Quality (EPA) Prescribed burn impacts and management

7 Georgia Tech Particulate Matter Concern due to health and visibility impacts Atlanta in non-attainment Complex mixture of solid and liquid particles suspended in the ambient air Size classifications “super-coarse” > 10μm “coarse” (PM 10 ) < 10μm “fine” (PM 2.5 ) < 2.5μm “ultrafine” < 0.1μm Many sources Many chemical species: Ozone (a gas) also of concern Health effects Atlanta is in non-attainment

8 Georgia Tech ASACA (GP funded) ASACA System of four monitoring locations around Atlanta Continuous PM 2.5 Daily PM 2.5 composition “Continuous” since 1999 Designed to Complement SEARCH Provide unprecedented spatial, compositional and temporal coverage in Atlanta SEARCH+STN+ASACA Provide data for Health (ARIES) Model evaluation Targets of opportunity (Fire!) Student (UG & Grad) training

9 Georgia Tech Capturing a Forest Fire February 28 th, 2007 3000 acre planned burned 70 km SE of Atlanta Winds shift PM levels climb from <10  g m -3 to over 150 in two hours Ozone jumps 20 ppb Bad for health, but Great opportunity to diagnose forest fire impacts ASACA composition data Fires appear to have greater impact than emissions inventories suggest Rich in OC, not EC Aging increases water solubility Simulated PM plume Observed PM Concentrations

10 Georgia Tech Air Quality Modeling Provide a virtual laboratory to better understand atmospheric dynamics and emission control impacts Applications Assess impacts of planned controls on attainment Fall line air quality study (FAQS) Impact of climate on air quality Understand how much the 2003 NE blackout impacted air quality Emissions Chemistry Air Quality/Health Impacts Control s Pollutant Distributions Air Quality Model Meteorology Air Quality Goals

11 Georgia Tech 36-km 4-km 12-km Air Quality Model Application Domain

12 Georgia Tech Impact of Planned Controls: 2000 vs. 2007 Planned emissions reductions lead to about a 10-20 ppb ozone reduction: Can we figure out which sources continue to be main contributors to nonattainment?

13 Georgia Tech Residual ozone from Atlanta sources apportioned by NO x category Contribution to Atlanta ozone (ppm) Atlanta NO x : Aggregate Atlanta NO x : By Category Cross- sens. Sum of parts Atlanta MSA, 8-hour ozone, Aug. 13-19, 2000 (Year 2007 emissions) 65% Linear

14 Georgia Tech Climate Impacts on Air Quality  Smog tends to get worse when it is warm…  Climate change is expected to make things warmer…  So, is air quality going to get worse? Complexity: Emissions will change, so what are the relative impacts (controls vs. climate change)

15 Georgia Tech Emission Changes Now 2050 no controls

16 Georgia Tech What “we” have done… Simulated how climate will impact air quality using large scale, 3D air quality models Focused on changes expected in about 2050 Included climate change impacts with and without emissions changes SMOKE (w/ 2001 EI) SMOKE (w/ 2050 EI) NASA GISS IPCC A1B MCIP CMAQ-DDM MM5 And the answer is…

17 Georgia Tech Impact of Potential Climate Change and Planned Controls on Ozone and PM 2.5 - Controls will significantly lower PM and Ozone -Ozone: 3-40 (maximum 8-hr) ppbV lower in 2050 (6-40%), PM~ 40% -Climate has a more limited impact -Ozone: +1ppbV, PM can go up or down standard

18 Blackout!

19 Georgia Tech Assessing the Impacts of the 2003 NE Blackout August 14, 2003 : Large scale blackout begins over parts of the Northeast, Midwest, and Ontario U. Maryland analyzes flight data, suggests drop in power plant emissions led to: 50% decrease in ozone @PA site 90% decrease in sulfate Challenges models to use this data set to evaluate ability to capture such changes EPRI analysis suggests not so fast GIT jumps in… Ozone impact 4% Large fraction from automobiles Sulfate impact 20% Much of the UM impact due to strange trajectory Came over Canada, not Ohio River Valley OzonePM 2.5
