The production of the sea ice thickness climate data record of the ESA Climate Change Initiative (CCI) has been finalized. The files are currently being registered with their respective doi's and official dissimination will commence shortly. 

The CCI sea ice thickness climate data record is based on 15 year of satellite radar altimeter data from Envisat and CryoSat-2 data and provides daily trajectory (l2p) and monthly gridded (l3c) observations between 2002 and 2017 in netCDF format. For the first time, the radar altimeter data record has been extended to the southern hemisphere with year-around freeboard and thickness retrieval which is possible due to the absence of melt ponds. The version of the product is v2.0 to indicate that this is the outcome of the second phase of the CCI project.


Mean monthly Arctic basin sea ice thickness in the winter month between October and April (within the Envisat orbit: < 81.45N)


Mean monthly Antarctic-wide sea ice thickness of the experimental climate data record for the southern hemisphere
