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…

Addressing wildfire is not simply a fire management, fire operations, or wildland-urban interface problem - it is a larger, more complex land management and societal issue. The vision for the next century is to: Safely and effectively extinguish fire, when needed; use fire where…
