Synergies between SWOT and L-Band sensors over wetlands

Résumé

Monitoring of inland water surfaces via remote sensing over tropical areas is a challenging task because of impact of vegetation and cloud cover. Surface Water & Ocean Topography (SWOT) mission will provide global monitoring of inland waters height and extent with high spatial resolution and a 21 days cycle. Several microwave based products have been elaborated to monitor these surfaces (Papa et al. 2010). Based on results during CAL/VAL of SMOS (Al Bitar et al. , 2012), new studies at CESBIO showed the potential of L-Band SMOS (Soil Moisture and Ocean Salinity) mission to monitor water surfaces in tropical areas under the vegetation at relatively high temporal scale (3-7days) but low spatial resolution (25km). In this project we aim at studying the synergistic potential of the use of SWOT futur data over wetlands with L-Band data from radiometers namely SMOS (ESA/CNES) and SMAP (Soil Moisture Active Passive – NASA).
