Speciated Seasonal over the Central EUS

The seasonal aerosol aerosol pattern at the IMPROVE sites is examined using two methodologies:

– Seasonal Mass Balance Charts

– Seasonal Percentile Frequency Charts

Method 1: Cumulative Seasonal PM2.5 Composition

• PM2.5 chemical components were calculated based on the CIRA methodology

• In addition, the the organics were (tentatively) further separated as Primary Smoke Organics (red) and Remainder organics (purple)

PSO = 20*(K - 0.15*Si – 0.02* Na) Remainder Org = Organics - PSO

• Also, the ‘Unknown’ mass (white area) is the difference between the gravimetrically measured and the chemically reconstructed PM2.5.

• The daily chemical composition was aggregated over the available IMPROVE data range (1988-99) to retain the seasonal structure.

• I order to reduce the noise the daily data were smoothed by a 15-day moving average filter.

Method 2: Seasonal Percentiles, 1992-99

At Lye Brook, VT, the clean days (20 percentile) corresponds to ~4 ug/m3 throughout the year

The dirty days are (80-90%-ile) have 2-5 times higher concentration than the clean days.

Dirty days, 80-90%

At the Smoky Mtn, the clean days in the winter are also ~4 ug/m3. However in the summer, even the ‘clean’ days have 14 ug/m3 PM2.5.

The dirty days are have 2-3 times higher than the clean days through out the year.

• The charts depict the magnitude of seasonal and synoptic variation• The synoptic-scale variation (day-to-day) can be measured by the 20-80 percentile spread

Regional Grouping of Sites

• For this presentation the IMPROVE sites were grouped as follows:

– New England ()

– Mid-Atlantic ()

– Central EUS ()

– Peripheral ()

• For each region, the seasonality is displayed for:

– Chemical Mass Balance

– Carbonaceous Mass Balance

– Fine Particle Mass Percentiles

– Coarse Mass Percentiles

– Sulfate Percentiles

– Fine Soil Percentiles

– Tot. Carbon. + 'Unknown' Percentiles

– Smoke Organics Percentiles
