Abstract

The NASA Soil Moisture Active Passive (SMAP) mission Level 4 Carbon (L4-C) product provides model estimates of Net Ecosystem CO₂ exchange (NEE) incorporating SMAP soil moisture information as a primary driver. The L4-C product provides NEE, computed as total respiration less gross photosynthesis, at a daily time step and approximate 14-day latency posted to a 9-km global grid summarized by plant functional type. The L4-C product includes component carbon fluxes, surface soil organic carbon stocks, underlying environmental constraints, and detailed uncertainty metrics. The L4-C model is driven by the SMAP Level 4 Soil Moisture (L4-SM) data assimilation product, with additional inputs from the Goddard Earth Observing System, Version 5 (GEOS-5) weather analysis and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data. The L4-C data record extends from March 2015 to present with ongoing production. Initial comparisons against global CO₂ eddy flux tower measurements, satellite Solar Induced Canopy Florescence (SIF) and other independent observation benchmarks show favorable L4-C performance and accuracy, capturing the dynamic biosphere response to recent weather anomalies and demonstrating the value of SMAP observations for monitoring of global terrestrial water and carbon cycle linkages.
