Snow depth estimation on leadless landfast ice using Cryo2Ice satellite observations by M. Saha, J. Stroeve, J. Stroeve, D. Isleifson, J. Yackel, V. Nandan, V. Nandan, J. C. Landy, H. M. Lam

“…In lieu of sea surface height estimates from leads, snow depths are retrieved using the absolute difference in surface heights (ellipsoidal heights) from ICESat-2 and Cryosat-2 after applying an ocean tide correction based on tidal gauges between satellite passes on 29 April 2022. Both the absolute mean snow depths and distributions retrieved from Cryo2Ice were slightly underestimated (2 to 4 cm) when compared to in situ measurements. …”
