## October 16: Canopy fire

- Clark-1996-CAM doi ucd p. 181 "... the heat flux from the ground fire first goes into drying the canopy. Once the canopy fuel is dry and the ground heat flux exceeds the threshold value of 170 kJ m
^{2}, the canopy ignites". The canopy fire does not appear to spread by itself. - Clark-2004-DCA doi ucd The same, plus "... The dry canopy mass corresponding to the change in fractional area of ground fire is burned and converted to latent and sensible heat..."
- Coen-2005-SBE doi ucd Also insertion length 50m (p. 3), and fuel mass and initial moisture ratio (p. 6) in the fuels used there.
- Estimating canopy fuels and their impact...

- Layman fuel reduction burn "unexpected" fire behavior really intense fire - not ROS. Convergence of winds into a very intense convection columns, then smoke shield spreads at some layer, unstable atmosphere. Crown scorch 70-80% (was to be max 20-30% for controlled burn)
- convection columns, low level wind convergence, potential instability (fireCape), dry air aloft
- WRF coupled Rothermel's (McArthur heavily dependent on temperature and humidity), 1km resolution, could not capture convection column
