3. ClearSky Plume Rise Field Study
Objective: Evaluate CALPUFF plume rise
Measure top of plume height
Collect meteorological data
Document burns visually (Photographs)
Methods
Aircraft measurements
Ground-based measurements
CALPUFF reruns

4. Field Burn Overview
76 to 122 Acres
Wheat Stubble & Kentucky Bluegrass

5. Final Results 2 underestimated plume height, slightly
2 - 3 overestimated plume height
Newer emission parameters increase plume rise

6. ClearSky Evaluation 2003 ClearSky Evaluation (Jain, 2004):
ClearSky is highly sensitive to Wind Speed & Wind Direction
Small differences in wind direction determine whether or not smoke plumes are predicted to affect an air quality monitoring station
How to represent the uncertainty coming from the meteorological conditions?
This motivated an Ensemble experiment! Heitkamp found that 12-km ECS was slightly better than 4-km original system. So, what about a 4-km ensemble?

7. Culture of Use? ‘Most probable’ results?

8. Current effort:. 3-D CALPUFF
Current effort: 3-D CALPUFF Windrose graphics Interested to do more with 1-km ClearSky…
ECY Contract Task 2 Assessment: How to get ClearSky ag-burning results into the regional PM results?
ClearSky and its use don’t necessarily provide realistic ag-burning emissions, nor PM2.5 results!
So we’ve proposed a 2004 burn season re-analysis to build met-forecast driven inference rules for ag-burning emissions for AIRPACT.
