The supplementary information contains three tables and seven figures that aid in the
explanation of methods and interpretation of results. 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. [2011] is shown in Figure S7.
