5% of the variability. PAH concentrations at these Great Lakes sites tend to be elevated when the wind is coming out of the south-southeast, and this factor represents about 1.2% of the variability. PAH concentrations are lower when the wind speed is higher; this is a significant but small effect, representing only about 0.17% of the variability.…[Read more]
