TY - GEN T1 - SiB4 Modeled Global 0.5-Degree Hourly Carbon Fluxes and Productivity, 2000-2018 AU - Haynes, K.D. AU - Baker, I.T. AU - Denning, A.S. DO - 10.3334/ORNLDAAC/1847 UR - https://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1847 AB - This dataset provides global hourly output predicted from the Simple Biosphere Model, version 4.2 (SiB4), at a 0.5-degree global scale covering 2000 through 2018. SiB4 is a mechanistic land surface model that integrates heterogeneous land cover, environmentally responsive phenology, dynamic carbon allocation, and cascading carbon pools from live biomass to surface litter to soil organic matter. Hourly output includes carbon fluxes, carbonyl sulfide (COS) fluxes, gross primary production, ecosystem respiration, solar-induced fluorescence (SIF), top-layer soil temperature and moisture, vegetation stress, photosynthetically active radiation (PAR), leaf and canopy-level carbon-dioxide partial pressures, and canopy conductance. The SiB4 output is per plant functional type (PFT) within each 0.5-degree grid cell. SiB4 partitions variable output to 15 PFTs in each grid cell that are indexed by the npft dimension (1-15) in each data file. The PFT three-character abbreviations (pft_names) are listed in the same order as the npft dimension. To combine the PFT-specific output into grid cell totals, users must compute the area-weighted mean across the vector of PFT-specific values for each cell. Fractional areal coverages are given in the pft_area variable for each cell. Note that values for fire carbon-dioxide emissions (resp_fireco2) are the total per grid cell and are not partitioned among plant functional types.
