Retracking Cryosat-2 Data in SARIn and LRM Modes for Plateau Lakes: A Case Study for Tibetan and Dianchi Lakes

This paper estimates lake level variations over two small and adjacent lakes in the Tibetan plateau (TP), namely Gemang Co Zhangnai Co, as well inland Dianchi Lake China using CryoSat-2 SARIn-mode LRM 20-Hz waveforms period of 2011–2018. Different retrackers a dedicated data editing procedure have been used to process for determining time series. The estimations are indirectly validated against those from Jason-2 TP situ Lake, both showing good agreement with strong correlation coefficients >0.74. results this suggest that official ICE retracker APD-PPT most appropriate lakes, respectively. trend series derived by 61.0 ± 10.8 mm/yr TP, 30.9 64.9 indicating levels three were continuously rising study period. show can be monitoring many not measured other altimetry missions TP.
