A coupled weather-fire forecasting model built on top of Weather Research and Forecasting (WRF). This is the original https://github.com/openwfm/wrf-fire transitioned to a fork of WRF and selected as ifire=1. Graphic log at https://repo.or.cz/git-browser/by-commit.html?r=WRF-SFIRE.git
The approximation in subroutine fuel_left does not vary the output smoothly enough resulting in spikes of the heat flux, which is constant times the time derivative of fuel left. For a reasonable approximation, the fire mesh needs to be very fine so that the fuel decay stretches over several cells and is approximately linear in each, but there will still be some artifacts when the wireline enters the cell at certain angles. Implement numerical quadrature for diagnostics and train a fast surrogate.
