Soil Moisture Active Passive (SMAP) L4 Carbon Ancillary Biome Parameter Look Up Table V001

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Metadata Last Checked: October 30, 2025 | Last Modified: 2025-03-31

This ancillary SMAP product contains biophysical characteristics (biome parameters) used to estimate carbon fluxes and soil organic carbon in the SMAP L4 Carbon algorithm. Biophysical characteristics were established from previous studies and the parameters defined for the MODIS MOD17 operation GPP algorithm. This data set was refined through regional and global comparisons and calibration of prototype SMAP L4 Carbon calculations.
