Fire Pixel Layer

• Fire Pixels show the location of fires

• Importing Fire Pixels into ArcGIS– Export from DataFed as a

CSV Table– Reformat as Excel table– Connect table through

ODBC/OLE DB connection in ArcCatalog

– Display XY in ArcMap

Aerosol Extinction Coefficient Layer

• Provided by Surf Met Network

• Measures the amount of haze

• Imported into ArcGIS the same way as the fire pixels– Displayed equal

interval quantities

Spatial Join: AE Coef. And County Shape file

• In DataFed AE Coef. is a grid dataset

• In ArcMap it is a point dataset

• Initial export of the grid was too coarse, changed the resolution

• Used spatial join to merge AE Coef. Point layer to county

High Average AE Coeff.• Shows the area that

has high AE Coeff. or surface haze.

• Created by using Select Attribute

GOCART Organic Carbon Model

• The model is used to identify composition of haze.

• It was imported into ArcMap and joined spatially to the AE Coeff./County layer

High Organic Carbon Values

• High model values indicate the presence of smoke

Smoke Identification

• The presence of both haze and high forecasted organic carbon indicate smoke in the area.

• This figure indicates that the model is only an estimate of where the smoke could be

Enlarged Smoke Impact Region

• Restated the query to include either high AE Coeff. or high organic carbon

• Better encompasses the smoke impacted region.

County Population

• Population for every county

• Joined county population to the Expanded Smoke Impact Region

Interpretation

• Using the AE Coeff. and OC Model with the satellite for verification the impacted region was identified.

•Smoke impact is determined by weighting the population with the concentration.
