Sea Ice Concentration v2.0 ECV is now available

Mon, 2017-03-06 12:47

The Sea Ice CCI team is pleased to announce the release of a full reprocessing of the Sea Ice Concentration (SIC) v2.0 ECV. The release provides Climate Data Record (CDR) of SIC over the polar regions, derived from medium resolution passive microwave satellite data of AMSR-E (2002-2011) and AMSR2 (2012-2015).

Two new CDRs are made available:
• The 25km SIC CDR based on 18.7 GHz and 36.5 GHz imaging channels (; Read more »

International Workshop on Remote Sensing of Sea Ice, 23-24 January 2017, Tokyo

Mon, 2016-11-28 15:57

The topic of the workshop is "Retrieval of Total Sea Ice Concentration from AMSR-E and AMSR2 Data using Optimal Estimation Techniques” with specific focus on (1) Next generation sea ice retrieval algorithms including optimal estimation of sea ice and other related geophysical parameters from microwave radiometer data, and (2) Linking between modeling and observational sea ice communities, especially for the development of next generation sea ice models, a natural ground for data assimilation.

The second progress meeting of SICCI Phase 2 was hosted by University of Hamburg and Max Planck Institute for Meteorology. The focus of the meeting was to review the progress of the new SIC and SIT data sets and status of deliverables by month 18. The agenda for the meeting is attached.

Sea Ice Drift KO meeting (12-13 January 2016)

Mon, 2016-01-18 14:32

The SICCI project team had a meeting to kick-off its sea ice drift activities. Hosted at IFREMER (Brest, France), the two-days workshop was aiming at reviewing and consolidating the plans and objectives for the investigations. The methodology to perform algorithm intercomparison was discussed, as well as the design of the Round Robin Data Package (RRDP). These will be further documented in a Product Validation Plan (due end of April 2016). The first results of the algorithm intercomparison are expected by Fall 2016... stay tuned! Read more »

Workshop on sea level in the Arctic, 15-18 June 2015

Thu, 2015-06-18 08:48

The workshop "Extension and Improvement of the Mean Sea Level estimation in the Arctic regions using space altimetry data” was organised by International Space Science Institute (ISSI) in Bern 15-18 June. The workshop brought together experts working with altimeter data in the Arctic in order to exchange information between the sea ice and sea level research communities. The workshop aimed to develop co-operation between the two expert groups by working together on common problems - namely sea ice and lead detection, retracking and local sea level anomaly determination.
