DSAWSP board member Dr. Dorothy Robinson has developed calibration equations for PurpleAir monitors that “provide accurate estimates of wood smoke PM2.5 pollution that are almost identical to those from the NSW government equipment.”

In a peer-reviewed research article published in the journal Atmosphere, Dr. Robinson concluded:

For most locations, calibrated PA PM2.5 are more accurate than those from a central monitor a few hundred meters away because spatial variation in wood smoke pollution is substantial and depends on local sources such as nearby wood heaters. More accurate exposure estimates allow improved estimates of both exposure–response relationships and health costs.
