Release of Sea-Ice Concentration Climate Data Record based on AMSR-E and AMSR2 satellite data
sea ice data users,
Sea Ice Climate Change Initiative team is pleased to announce
the release of a full reprocessing of the Sea Ice Concentration
(SIC) v2.0 Essential Climate Variable (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 (June 2002 - September 2011) and AMSR2
(July 2012 - December 2015).
two SIC CDRs use different imaging channels and therefore they
have different characteristics and accuracies. Initial
validation work indicates that the 50km CDR has higher accuracy
than the 25km CDR across the range of sea ice concentration
values, however, it has lower spatial resolution. Compared to
similar SIC CDRs available e.g. from EUMETSAT OSI SAF or NSIDC,
the SICCI 25km CDR has finer spatial details, especially in the
ice edge region due to the finer spatial resolution of the
AMSR-E and AMSR2 data used here.
two CDRs were generated in the context of the ESA Climate Change
Initiative Programme (ESA CCI) by the Sea_Ice_CCI project (www.esa-seaice-cci.org).
The EUMETSAT OSI SAF contributed with access and re-use of part
of its processing software and facilities.
parallel, please note that the EUMETSAT OSI SAF is preparing a
new version of their global SIC CDR, using some algorithms
developed during ESA CCI. The new OSI SAF CDR covers years 1979
to 2015 and is processed from instruments with coarser spatial
resolution (SMMR, SSM/I, and SSMIS). Its release will be
announced on www.osi-saf.org.
With apologies for potential cross-postings I
remain with best regards on behalf of the SICCI project team!
