Title
High resolution mapping of inundation area in the Amazon basin from a combination of L-band passive microwave, optical and radar datasets
Abstract
•SWAF-HR data is new water surface extent product at 1 km over the Amazon basin from 2010 to 2016 every 3 days.•SWAF-HR provided from the fusion of three datasets: water surface fraction at coarse spatial resolution from an L-band passive microwave sensor (Soil Moisture and Ocean Salinity – SMOS), Global Surface Water Occurrence from Landsat (GSWO) and the Digital Elevation Model (DEM) Multi-Error-Removed-Terrain (MERIT) based on the Shuttle Radar Topography Mission.•The flooded area of the Branco floodplain (Roraima) varies from 0.2times104 to 2.7 × 104 km2 whereas the extent of the Bolivian floodplain (Llanos de Moxos) inundation ranges between 0.8 × 104 and 8.1 × 104 km2 during 2010–2016.•The choice of the DEM in the downscaling process introduces 5% of error in the instantaneous water surface extent estimate but can reach up to 10% in the flood probability estimations over seven years.•(MERIT) based on the Shuttle Radar Topography Mission (SRTM).
