[edit] Event Evidence Analysis

[edit] Chemical Signature:

For the Chesterfield site (450250001) chemical composition data for March 6, 2002 are not available. The surrounding stations in the southeastern U.S. do not indicate a regional scale SmokeBioMass episode. The NAAPS model SO4 surface concentration estimate shows the highest values north of the Ohio River Valley.

[edit] Fire and Transport:

The satellite data indicate isolated fire pixels over the southeastern U.S. The satellite Aerosol Optical Thickness, AOT, also shows isolated small plumes, 5-10 km width oriented from the southwest to the southeast.

[edit] Spatial Pattern:

The fine mass concentration shows that Chesterfield, SC (near Charlotte, NC) has exceptionally high PM2.5 (41 mg/m3) compared to the surrounding stations (<15 mg/m3).

[edit] Temporal Pattern:

The time series for Chesterfield indicate that March 6, 2002 shows exceptionally high PM2.5 concentration (41 mg/m3) compared to other times, prior and after the event.

[edit] Event Summary:

The high PM2.5 concentration at Chesterfield on March 6, 2002 is an anomaly in both spatial and temporal pattern which is consistent with the impact from a nearby smoke source. This exceptional value is supported by the satellite AOT which indicate small plumes originating from nearby fires.
