Time series of terrestrial ecosystem carbon stocks and fluxes, snow cover and organic layer moisture from 1901 to 2100 for Alaska and Northwestern Canada

Time series graphs of the soil and vegetation carbon pools (grams Carbon/meter squared) and main carbon fluxes (gC/m2/yr), snow depth (m), organic layer thickness (m) and moisture (m3/m3) from 1901 to 2100. Vegetation carbon stocks only concern living biomass. Soil carbon stocks include organic layer, 1m deep mineral layers and dead woody debris. Carbon fluxes are vegetation Net Primary Productivity (NPP), Gross Primary Productivity (GPP), soil Heterotrophic respiration (HR) and fire emission from organic layer and vegetation burning. Annual vegetation and soil carbon stocks are estimated for the month of December. Annual carbon fluxes, organic layer thickness and moisture are averages of monthly estimates. Annual snow thickness corresponds to the maximum monthly estimate per year.

All variables are averages of outputs from the Terrestrial Ecosystem Model for Alaska and Northwestern Canada at a 1km resolution. Historical records start in 1901 and end in 2009 (black solid line), projections start in 2010 and end in 2100 (dark red solid and dotted lines). Projections have been conducted for two climate models for the A1B emission scenario of the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios Assessment Report 4 (IPCC-AR4). The two global circulation models used for these projections are (1) the 5th generation of the ECHAM general circulation model from the Max Planck Institute for Meteorology (MPI-ECHAM5/MPI-OM, dark red dotted line), and (2) the fourth generation global circulation model from the Canadian Centre for Climate Modelling and Analysis (CCCMA-CGCM3.1(T47), dark red solid line).
