ResumoThe C3/C4 composition of vegetation is required for a diverse set of carbon cycle research, including inversion studies that use global CO2 and ä13C atmospheric data, as well as work that requires the carbon isotope composition of biomass burning emissions. Here, we present continental maps of the abundance and distribution of C3 and C4 vegetation for South America. Our approach relies upon the near-universal restriction of C4 photosynthesis to the herbaceous growth form and the differing performance of C3 and C4 plants in various temperature and radiation regimes. The MODIS Vegetation Continuous Fields (VCF) product provides detailed information on growth form composition (% tree, % herbaceous, and % bare) for each grid cell; precipitation and temperature variations are derived from station data climatologies; and crop type fractional coverage accounts for managed agro-ecosystems that may violate the natural climate constraints. A major limitation of the MODIS VCF product is that the vegetation layers do not directly correspond to the percent woody and percent herbaceous cover layers that are needed to accurately derive C3/C4 composition of vegetation cover. To address this issue, we develop a rules-based algorithm to separate shrubs and true herbaceous cover from the MODIS herbaceous (i.e., non-tree vegetation) layer using the Global Land Cover 2000 dataset for South America. The ä13C content of vegetation in South America is then estimated based on the C3/C4 composition in each land grid cell, assuming constant values of -27 and -12 for C3 and C4 plant biomass, respectively.
