Short summary
Woodsmoke is a worldwide public health concern. A reliable marker for woodsmoke will be very useful in air-quality management. DC (Delta-C) has been proposed as a woodsmoke marker in previous studies. However, several researchers raised concerns of whether it is reliable. Our study took advantage of aerosol light absorption and PM2.5 data collected at three US cities/towns dominated by woodsmoke. We showed that DC can be a good qualitative and semi-quantitive marker, but with limitations.
