Principle Investigator: Aaron Boone (CNRS/LEGOS)

Co-Investigator(s): Melanie Trudel, Jean-Francois Cretaux, Manon Delhoume, Claire Pottier, Daniel Lee Peters, Gabriela Siles, Alexei Kouraev, Fabien Blarel

The SNORKS2 project focuses on lakes in Canada, especially over the Quebec province and the Peace-Athabasca Delta (PAD). Its objectives cover two aspects: 1- analyze and better understand the new SWOT data/products, associated uncertainties, main limitations and the impact of phenology and especially ice, snow, vegetation and precipitation on these products; 2- compute lakes and reservoirs mass balance and analyze the connectivity with rivers. Feedback will also be provided to CNES and JPL SWOT project team on lakes products.

Congo - Aaron Boone — Performances of the assimilation of SWOT-like data into the CTRIP river routing model over the Congo Basin after a 21-day cycle. The color corresponds to the assimilation index that describes the improvement (in blue) or degradation (in red) provided by the assimilation in comparison to a simulation without data assimilation.
