Description

The SMOS-CryoSat merged Sea Ice Thickness Level 4 product, in NetCDF format, is based on estimates from both the MIRAS and the SIRAL instruments with a significant reduction in the relative uncertainty for the thickness of the thin ice.

A weekly averaged preliminary product is generated every day by the Alfred Wegener Institut (AWI) by merging the weekly CryoSat Sea Ice Thickness product and the daily SMOS Sea Ice Thickness retrieval. A final product is provided with a latency of about 3-4 weeks using a different global sea ice concentration product and a reprocessed CryoSat product.

All grids are projected onto the 25 km EASE2 Grid based on a polar aspect spherical Lambert azimuthal equal-area projection. The grid dimension is 5400 x 5400 km, equal to a 432 x 432 grid centered on the geographic Pole.

Coverage is limited to the October-April (winter) period for the Northern Hemisphere, due to the melting season, from year 2010 onwards.
