The aim of the SMOS-NEE project is the development of a Level 4 Net Ecosystem Exchange (NEE) product based on the assimilation of Level 3 Soil Moisture and Ocean Salinity (SMOS) soil moisture into the Carbon Cycle Data Assimilation System (CCDAS). The SMOS satellite mission has been providing global observations of soil moisture and other products since early 2010. Net Ecosystem Exchange (NEE) is the net uptake of atmospheric CO2 by the terrestrial biosphere.
The Carbon Cycle Data Assimilation System (CCDAS) is a modelling tool that can systematically assess the strength of observational constraints on terrestrial carbon and water fluxes. The study will modify CCDAS to enable the assimilation of SMOS Level 3 soil moisture and thus quantify the added value of the L3 product in reducing uncertainties in simulated NEE. The consistency between local soil measurements of soil moisture and carbon fluxes, atmospheric CO2 concentrations and CCDAS simulated NEE will also be assessed.
The project started in Febuary 2013 and is funded by the European Space Agency.
