ARVE-Research/LPJ-LMfire: Oxygen-Fire

10 September 2022

This is the version of the LPJ-LMfire code used in experiments described in the manuscript:

Vitali, R., Belcher, C. M., Kaplan, J. O., & Watson, A. J. (in review). Redefining the fire window: Higher atmospheric oxygen concentrations are compatible with the presence of forests. Nature Communications.

In this version of the code, ignition efficiency, moisture of extinction, and heat of combustion in the spitfiremod.f90 module are influenced by prescribed ambient atmospheric oxygen concentrations. Changing O₂ concentrations leads to changes in burned area, biomass, and vegetation cover, with higher O₂ generally leading to an increase in fire and decrease in woody vegetation cover.

For further details, the authors can be contacted for a preprint of the manuscript.
