Preparing for the Ingestion of SWOT Data into Continental-scale River Models [poster]
David, C.H., Andreadis, K.M, Famiglietti, J.S., Beighley, R.E., Boone, A.A., Yamazaki, D., Kim, H., Gaborit, E., Rodriguez, E., Biancamaria, S., Paiva, R., and Schumann, G. J-P. (13-Dec-16). In preparation for the expected SWOT observations, an inter-comparison of continental-scale river models is being designed. We present here the preliminary architecture and early results of the inter-comparison in hope to motivate further community feedback and involvement.

Developing a Global Assimilation and Modeling Framework to Produce SWOT Data Products
PI: Kostas Andreadis (15-Jun-17). Our project aims to develop a modeling and data assimilation framework that can be implemented efficiently for generating a SWOT Level 4 data products consisting of continuous fields of water surface elevation, discharge, and storage change globally.
