Gridded Observational Sea Ice Thickness Products, Version 1

Fields of long-term mean spring ice thickness derived from ERS-1 (1993-2001) and CryoSat (2011 to 2013) radar altimeters, ICESat laser altimeter (2004 to 2009), Operation IceBridge airborne altimeter and snow radar (2009 to 2014), and submarine upward looking sonar (1986-) are provided on 100 km EASE grids. All satellite-derived ice thickness fields were regridded as needed from their original gridded format to 100-km EASE grids using a drop-in-the-bucket averaging. IceBridge and submarine thickness estimates within 70 km of a 100 km EASE grid box center were averaged to give a grid cell mean thickness.
