Empirical evidence of overestimated Ku-band sea ice radar freeboards in satellite altimetry

Abstract. Pan-Arctic sea ice thickness estimates are routinely produced from Ku-band radar altimetry observations. State-of-the-art waveform retracking algorithms rely on the uncertain assumption that Ku-band radar waves penetrate through the snow and that the dominant return ori...

Year-Round High-Resolution Sea Ice Freeboard Retrieval Using ICESat-2 ATL03 Photon Data

Abstract. Arctic sea ice freeboard is critical for estimating ice thickness and characterizing surface morphology, yet it remains poorly constrained, especially during the melt season due to limitations in conventional altimetry products. The ICESat-2 ATL07 product retrieves surf...
