Lake Monitoring from a Combination of Multi Copernicus Missions: Sentinel-1 A and B and Sentinel-3A
Author(s): Shirzad Roohi, Arash Amini, Behzad Voosoghi,and Douglas Battles
Monitoring water volume changes of a given lake needs precise estimation of water level and water surface variations. The water level of the lake might be erroneous due to multi reflections, called multi peak waveforms, from the illuminated area inside the radar footprint. Bathymetry data are also not available everywhere to measure the absolute water volume storage.
To derive optimized ranges and consequently more precise water level, corrupted waveforms need to be analyzed. We developed a new approach to select an optimal peak in a given waveform to be retracked with the threshold retracker. We selected a peak, which provides a water level closest to the in situ gauge. In another scenario, we involved all meaningful peaks in a given waveform and considered the average of ret... view more»
