Table S1 outlines the parameters we used for reconstructing pre-fire carbon contents in burned soil cores. Table S2 provides information on all the Landsat images we used. Table S3 outlines the values or methods we altered for our assessment of uncertainty. Figure S1 displays relationships between depth of burn and combustion in our burned soil cores. Figure S2 provides an example of how our terrain corrections modified surface reflectance. Figure S3 shows the relationship between below- and aboveground combustion at our field sites. Histograms of differenced Normalized Burn Ratio (dNBR) and modeled combustion within the Gilles Creek fire perimeter are given in Figure S4. Results from modeling emissions using increases in spring albedo are displayed in Figure S5. Figure S6 shows how the Composite Burn Index (CBI) related to combustion and dNBR. Relationships between depth of burn and dNBR for our study sites and a collection of field sites from Turetsky et al.  is shown in Figure S7.
