Abstract

The NASA SMAP mission has a projected 2014 launch and will provide global mapping of surface soil moisture and freeze/thaw conditions using L-band (1.26 GHz) active and passive microwave remote sensing. SMAP science objectives include reducing uncertainty regarding land-atmosphere carbon exchange. An operational level 4 carbon (L4-C) product is planned for quantifying surface soil carbon stocks and net ecosystem CO₂ exchange (NEE) using model assimilated SMAP measurements with ancillary land cover and vegetation productivity inputs. We conducted an initial global implementation of the L4-C algorithms using MODIS productivity inputs and MERRA reanalysis daily soil moisture and temperature fields. The L4-C simulations are generally consistent with the distribution and magnitude of soil carbon stocks from global soil inventories. A model uncertainty analysis indicates anticipated NEE product accuracy within 30 g C m² yr^-1 (1.6 g C m² day^-1) and similar to accuracies attained from tower measurements.
