NSIDC DAAC Updates Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Data Set

8 November 2017

The Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS data set available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has been updated to Version 3.

The following changes were made to this version of data:

  • Inter-calbration techniques between SMMR and F08, as well as F08 and F11 where changed to match sea ice area rather than sea ice extent
  • Ocean tie points now change each day (similar to the ice tie points) based on brightness temperatures for that day
  • The threshold for the lower limit for ice was relaxed to allow retrieval of ice at 10 percent ice concentration
