Background: The record number of wildfires in the United States in recent years has led to an increased focus on developing tools to accurately forecast their impacts at high spatial and temporal resolutions.
Aims: The Warn-on-Forecast System for Smoke (WoFS-Smoke) was developed…

In an effort to reduce CO2 emissions from fossil fuel burning, renewable energy policies incentivize use of forest biomass as an energy source. Many governments have assumed (legislated) the carbon flux from burning biomass to be neutral because biomass growth sequesters CO2.…
