Data sets

NOAA Climate Data Record of AVHRR Polar Pathfinder Extended (APP-X), Version 1 [October–April, 2010–2018] J. Key, X. Wang, Y. Liu, and NOAA CDR Program

IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Quick Look, Version 1 [March-April, 2012-2017] N. Kurtz

CryoSat-2 Level-4 Sea Ice Elevation, Freeboard, and Thickness, Version 1 [October-April, 2010-2018] N. Kurtz and J. Harbeck

Short summary
We assess 8 years of sea ice thickness observations derived from measurements of CryoSat-2 (CS2), AVHRR and SMOS satellites, collating key details of primary interest to users. We find a number of differences among data products but find that CS2 measurements are reliable for sea ice thickness, particularly between ~ 0.5 and 4 m. Regional comparisons reveal noticeable differences in ice thickness between products, particularly in the marginal seas in areas of considerable ship traffic.
