Refined inland waveform retracking
The complex shaped inland altimeter waveforms do not satisfy the Brown model for ocean waveforms in most cases. As a result, they have to be subjected to an additional processing step, called retracking, in order to infer reliable and accurate water levels. Even though a variety of different retracking algorithms exist, most of them are tuned to specific applications (e.g. ocean, small lakes and narrow rivers) or missions. The goal of this project is to come up with one (best) retracker that is applicable for all inland waters and all altimetry missions while providing consistent and unbiased heights that can be used for further processing in the RU. The project will focus on the improvement of the existing ALES+ retracker algorithm.
