An Earth Observation Land Data Assimilation System (EO-LDAS)

► Monitoring of terrestrial ecosystems using Earth Observation data is often ill-posed. ► This can be improved by Data Assimilation with biophysical/empirical process models. ► A prototype DA system for land surface has been developed: EO-LDAS. ► With synthetic Sentinel2 MSI sampling we show improvements by a factor of 2 using DA. ► These results are quite robust to data gaps from clouds.
