NARSTO PM Assessment NARSTO PM Assessment Chapter 5: Spatial and Temporal Pattern TOC Introduction Data Global Pattern NAM Dust NAM Smoke NAM Haze NAM Total PM Local PM Speciated Seasonal over the Central EUS TOCIntroductionDataGlobal PatternNAM DustNAM SmokeNAM Total PM 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 methodologyCIRA methodology In addition, the the organics were (tentatively) further separated as Primary Smoke Organics (red) and Remainder organics (purple) PSO = 20*(K *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 ( ) to retain the seasonal structure. I order to reduce the noise the daily data were smoothed by a 15-day moving average filter. Shenandoah
Method 2: Seasonal Percentiles, 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. Great Smoky Mtn. Lye Brook Clean days (20%) ‘Clean’ days (20%) 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 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
