Arctic sea ice thickness information has been updated with NRT data for December 2017 and reprocessed data for November 2017. Daily, weekly and monthly products are available here: Reprocessed, Near-real time

Missing Input Data

CryoSat-2 NRT Level-1b input data was not available for December 16-17 on the ESA server. No sea ice data is available for these dates, which may affect estimates of sea ice volume and volume gain below.
