Slide 29 of 31
Notes:
Limited US fine particle mass and sulfate data are available from several Northeastern US sites (from the NESCAUM NEPART network) on August 26 and 28. While concentrations are much higher than average at these sites on August 26, there are much higher yet on August 28. A peak fine mass concentration of greater than 80 micrograms per cubic meter (half of which was sulfate) was observed at the remote Quabbin, Massachusetts on the 28th!
