Fig. 6. Intra-fire effects of forest biomass on fire severity across topographic slope and climate gradients.

Subsets depict how intra-fire (i.e. per fire) fuel-severity relationships change across topo-climatic contexts. Specifically, for each wildfire possessing a significant intra-fire linear effect between biomass and severity, its per-fire regression slope coefficient (AGBD~dNBR β₁) was regressed against mean values of (a) slope; (b) temperature seasonality (T_seas); (c) cumulative Gross Primary Productivity (GPP_cum); and (d) aridity index (AI) - each corresponding to the entire spatial extent of each fire. See Table 1 for variable descriptions and Table S1 for labeled fire abbreviations for panel (a).
