The CARbon DAta MOdel fraMework (CARDAMOM; Bloom et al., 2015 in review) outputs are derived from a global 1-degree x 1-degree 2001-2010 model-data fusion (MDF) analysis. The datasets include allocation fractions (AF) residence times (RT), mean carbon pool stocks (CP) and fluxes (FL). A list of files and their contents is provided below.
The Data Assimilation Linked Ecosystem Carbon model version 2 (DALEC2) and the Markov Chain Monte Carlo MDF algorithm are described by Bloom & Williams (2015); the fire module is described by Bloom et al., (2015; in review). Data constraints used in the CARDAMOM analysis consist of MODIS leaf area index (LAI), Harmonised World Soil Database (HWSD; Hiederer & Kochy, 2012) and tropical biomass (Saatchi et al., 2011). For each 1-degree x 1-degree gridcell, the metrics (e.g. mean, median, etc.) are based on 4000 DALEC2 model parameter samples unique to that grid-cell.
We note that the full 2001-2010 CARDAMOM output amounts to roughly 10 TB in binary format. For the sake of brevity, we have limited the following datasets to the subset presented in Bloom et al., (2015, in review). Additional MDF outputs can be made available upon request.
