Reprocessed NASA IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Arctic data are now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The IceBridge L4 Sea Ice Freeboard, Snow Depth, and Thickness (IDCSI4) product is informally regarded as Version 2 of the IceBridge Sea Ice Freeboard, Snow Depth, and Thickness (IDCSI2) product. Adding L4 (Level-4) to the data set name more accurately represents the data processing level. Currently, the reprocessed L4 data include Arctic campaigns from 2009 to 2012. Reprocessed Antarctica data are forthcoming.
This data set contains derived geophysical data products including sea ice freeboard, snow depth, and sea ice thickness measurements in Greenland and the Arctic retrieved from IceBridge Snow Radar, Digital Mapping System (DMS), Continuous Airborne Mapping By Optical Translator (CAMBOT), and Airborne Topographic Mapper (ATM) data sets.
For details on changes made between Version 1 (IDCSI2) and Version 2 (IDCSI4), see the Operation IceBridge sea ice freeboard, snow depth, and thickness data products manual, version 2 processing document. See the IceBridge L4 Sea Ice Freeboard, Snow Depth, and Thickness landing page for further information.
