Model code for reconstructing biomass burning emissions from ice core records of acetylene, ethane, and methane

Biomass burning emissions of trace gases are inferred from ice
core levels of acetylene, ethane, methane and its stable isotopes over the
last 1,000 years (Nicewonger et al., 2018, 2020). In Nicewonger et al.
2020 JGR-A, we attempt to reconcile the individual biomass burning records
from each trace gas into a single fire history of dry matter burned over
the last 1,000 years. We find that temporal trends in fire
inferred from the three trace gas records are in reasonable agreement for
the past millennium. However, the trace gas records do not yield a
quantitatively consistent fire history even when assuming dramatic changes
to the spatial location of fires and to the type of biomes through time.
This dataset includes the MATLAB scripts used to calculate biomass burning
emission histories for each of the gases: acetylene, ethane, and methane.
An Excel file included has the ice core methane and 13CH4 values used in
this study. Please refer to the original manuscripts and datafiles located
under the README tab for information on the methane
data.
