The panarctic CARDAMOM outputs are derived from 1°x1° degree model-data fusion (MDF) analysis for 2000-2015. In each pixel, the DALEC2 ecosystem model is constrained by MODIS Leaf Area Index, Northern Circumpolar Soil Carbon Database (Hugelius et al., 2013) and biomass estimates (Carvalhais et al., 2014) using a Monte-Carlo Markov Chain (MDF) method. DALEC2 and the MDF approach are described in Bloom and Williams (2015) and Bloom et al. (2016). This dataset includes four netCDF files which report pixel-wise mean annual land-atmosphere carbon fluxes, carbon allocation to plant parts, vegetation and dead organic matter carbon pool sizes and transit times. Files include the pixel-wise uncertainty by reporting the median value as well as bounds of the 95%, 90% and 50% confidence intervals. References - Bloom, A. A., Exbrayat, J.-F., van der Velde, I.
