Transport of Ozone and Precursors
The format in which the questions are presented reflects four points of view:
Specific technical question to the OTAG/AQA work group
Policy Question: The corresponding policy question
Rationale: Rationale and background for the question
Possible Answer: Possible answers - ‘lose cannon’, provocative answers
-
What are the nonattainment regions where transport of regional ozone is significant?
-
- Policy Question:
Is the transport of regional ozone a problem over the entire Eastern US?
-
- Rationale:
It is necessary to know where regional ozone transport occurs in order to address the problem
- Possible Answer:
Tranport of regional ozone is only significant in New Jersey

For how many days do airmasses carrying ozone and/or ozone precursors tend to persist within the OTAG domain?
-
- Policy Question:
How long do ozone problems last?
-
- Rationale:
to help decide how far out to control
- Possible Answer:
2-4 days, depending on temperature, rain, etc.

To what degree is NA in a given area is influenced by transport from outside?
-
- Policy Question:
What are the relative contributions of local and regional ozone
-
- Rationale:
A bottom line science question for OTAG.
- Possible Answer:
Control local sources 1 %, regional 99 % - it’s them doing it!

What are the conditions (space, time, meteorology) conducive for transport?
-
- Policy Question:
Can we use a space-time uniform policy?
-
- Rationale:
Does long range transport happen at odd locations and times or it is chronic
- Possible Answer:
Control only RTP, NC - it is responsible for everything

What is the distance (seasonal, directional) over which emissions influence NA sites?
-
- Policy Question:
What is the ozone precursor region of influence, China?
-
- Rationale:
We do not really know the ozone region of influence
- Possible Answer:
Control within 500 km, leave the rest.

What is the magnitude of regional ozone outside NA areas?
-
- Policy Question:
Is ozone from outside the NA area significant compared to ozone in NA areas?
-
- Rationale:
Regional ozone is there for sure, but how much?
- Possible Answer:
42 ppb!
