20% Best and 20% Worst Visibility Day Deciview Trends
• RH data available on the IMPROVE (http://vista.cira.colostate.edu/improve/Data/IMPROVE/summary_data.htm) and VIEWS (http://views.cira.colostate.edu/web/DataWizard/) websites.
• Data used in the plots for this presentation is the most recent (December 2011) QA’d data using the new revised IMPROVE algorithm
• The following set of plots compare monitored deciview values for the 20% best and worst visibility days with natural background, the Uniform “glide path” to natural conditions for the 20% worst visibility days and the CMAQ modeled 20% worst and best days “glide paths” from the baseline period to 2018.

As states near the mid course review, are deciview levels showing
reasonable progress?
• For the 20% best visibility days all sites are trending below their “glide path” and many sites are currently significantly below their respective Uniform and CMAQ 2018 “glide path” levels
• Visibility during the 20% best visibility days are not degrading
Light Extinction Contribution Trends• The following set of slides show the relative
contributions to light extinction for the 20% best and 20% worst visibility days due to the following particles in the atmosphere:– Ammonium sulfate– Ammonium nitrate– Organic mass– Light absorbing carbon– Fine Soil– Sea Salt– Coarse Mass (PM10) – Total particle (PM2.5 and PM10)– Rayleigh scattering

• Current (2006-10) contribution to light extinction due to sulfates continues to dominate (55-78%) at all sites with the highest contribution at sites in Virginia and West Virginia. (note this is down from 60-82% during the 2000-04 baseline period)
• Contribution to light extinction organic mass is the second highest at most sites (nitrates at Brigantine) and is not much higher than due to Rayleigh scattering.
• Contribution to light extinction from all other particle pollutants is the same or lower than due to Rayleigh scattering at all sites.
20% Best Visibility Days
• Contribution to light extinction due to Rayleigh scattering (56-68%) dominates at all northern sites with sulfates contribution second at 18-24% with organic mass third at 4-9%.
• Contribution to light extinction due to sulfates (31-40%) and due to Rayleigh scattering (29-37%) dominate at all southern sites sites with organic mass third at 7-11%.
