| Abstract describing the data | |
| Data Identification Abstract | Water level was estimated, using radar altimetry, over the major Indian inland water bodies over the duration 2008-2019 using modified algorithms specifically for inland water bodies. The methodology was based on waveform classification, waveform retracking, and dedicated inland range corrections algorithms. |
| Data Quality | |
| Accuracy | Over one of the test site, Ukai reservoir, the altimeter retrieved water level results were validated with the GPS survey and in situ gauge dataset. The results were found to be in good agreement with an overall root-mean-square error <15 cm. |
