Controls on variations in MODIS fire radiative power in Alaskan boreal forests: Implications for fire severity conditions

► Fires are sorted by vegetation, seasonality, fire activity level, spread behavior. ► Fronts are sorted from residual fires in active fire detections based on location. ► Higher fraction of residual burning lowers intensity of high fire activity periods. ► More late season and residual burning makes large fire years are more severe.
