Agriculture is a vital part of the Northwest’s economy and is critical to the region’s rural communities. The production cycle of cereal crops and grasses, which are important agriculture products of the Northwest, includes burning fields of post-harvest residue such as wheat stubble. Like smoke from forest fires, smoke produced by agricultural burning can have harmful effects on public health. To protect public health, smoke management agencies of the Northwest regulate agricultural burning by deciding how much, if any, field burning can occur on a given day. They use air quality forecasting models that predict the amount and composition of smoke produced and the dispersion of the smoke and its concentration at population centers. Smoke managers have reported that the models do not work well under certain conditions, resulting in significant smoke impacts on local populations. The developers of the air quality models and smoke managers need an extensive dataset of in situ observations of agricultural smoke production and dispersion in order to improve these critical air pollution forecasting tools.
