Presented to the 67th Joint Advisory Committee meeting
September 22, 2016

2. Overview Who: New Mexico State University & St. Edwards University
What: Design and conduct a program to collect ozone for the characterization and understanding of physico-chemical processes involved in the formation and destruction of tropospheric ozone in El Paso
Funded by TCEQ
When: Summer 2017

3. Project Goal
To characterize ozone in and over El Paso through an intensive observation and monitoring study during the summer of 2017

4. Monthly Ozone Concentrations
Mean
Highest mean monthly concentrations in AMJ but maximum highest in JAS
High mean AMJ may indicate regionally transported contributions
High maximum JAS can indicate local sources, nighttime titration
Maximum

5. 2008
2009

2014
“high” above defined as the 8-hr concentrations above 80th percentile

6. Objectives
Characterize ozone and meteorology aloft during episodes and throughout the ozone season
weekly ozonesondes and during episodes
Supplement existing surface ozone and meteorological monitoring network
2B Technology ozone sensors and portable weather stations

7. Ozonesonde
Collects vertical profile of weather and ozone from ground to stratosphere
Ozone sensor connected to radiosonde

8. Objectives
Assess vertical mixing of ozone from the free troposphere into the planetary boundary layer and assess/describe the meteorological conditions associated with this mixing
Assess the representativeness of the collected ozonesonde data set using satellite data and other sources
Identify temporal patterns and similarities and differences among the ozone monitoring sites

9. Objectives
Identify meteorological patterns and investigate the spatio-temporal variation of ozone and its precursors
Investigate the impact of smoke events using a combination of satellite remote sensing products and atmospheric transport models
Determine the potential for and perform a source attribution analysis using data collected as part of this study

10. Monitoring Locations
Augment existing network “backbone” with addition met and ozone sensors
Network design to help find peaks, transport patterns, and for specific receptors

11. Current Status Completing scope of work, send to MPO
Draft complete monitoring study and QA plan
Specifying monitoring technology
Recruiting students for summer 2017
Schedule training for spring 2017

12. For the JAC Support for the study and participants
Cooperation and assistance in site selection and permitting
