An Analysis of ICESat-2, PALSAR-2 and Sentinel-1 Data for the Assessment of Inundation Characteristics in the Amazon Basin

This study presents a preliminary assessment of vegetation and inundation characteristics in the Amazon basin using ALOS-2 PALSAR-2 L-band SAR and Sentinel-1 C-band SAR backscatter combined with ICESat-2 Lidar photon height data. Key Findings: –Photon height from ICESat-2 found useful to capture seasonal water level variations along major rivers and open water areas. –Comparisons between Lidar photon height and L- and C-band backscatter along forest-river transects show good agreement for the wet and dry seasons.
