Arctic and Antarctic sea ice thickness climate data record (ERS-1, ERS-2, Envisat, CryoSat-2)

Sea ice thickness climate data record based on altimetry missions : ERS-1, ERS-2, Envisat and CryoSat-2.
Data are available as EASE2-grid monthly maps with a spatial resolution of 12.5 km covering the period 1994-2023.
The dataset also includes radar freeboard, sea ice freeboard, total freeboard, sea ice thickness as well as external variables such as sea ice density and sea ice concentration.
Uncertainty are estimated using an ensemble approach and are distributed as statistics on the corresponding ensemble (mean, median, std, quantiles and percentiles).
