Validation of the multi-mission altimeter wave height data for the Baltic Sea region [PDF]
Estonian Journal of Earth Sciences, 2016 We present a complete cross-validation of significant wave heights (SWH) extracted from altimetry data from all ten existing satellites with available in situ (buoy and echosounder) wave measurements for the Baltic Sea basin.

Long‐term Caspian Sea level change
Geophysical Research Letters, 2017 Caspian Sea level (CSL) has undergone substantial fluctuations during the past several hundred years. The causes over the entire historical period are uncertain, but we investigate here large changes seen in the past several decades. We use climate model‐
