CERA-20C: ECMWF's Coupled Ocean-Atmosphere Reanalysis of the 20th Century
Years of record
- to
The CERA-20C is a global, coupled reanalysis spanning 1901-2010 with a focus on low-frequency climate variability. Similar to ERA-20C, the surface observations assimilated include surface pressures from the International Surface Pressure Databank v3.2.6 and ICOADS v 2.5.1, and surface winds over the oceans from ICOADSv2.5.1. Upper-air and satellite data are…

Merged Hadley-NOAA/OI Sea Surface Temperature & Sea-Ice Concentration (Hurrell et al, 2008)
Years of record
- to
The merged Hadley-OI sea surface temperature (SST) and sea ice concentration (SIC) data sets were specifically developed as surface forcing data sets for AMIP style uncoupled simulations of the Community Atmosphere Model (CAM). The Hadley Centre's SST/SIC version 1.1 (HADISST1), which is derived gridded, bias-adjusted in situ observations, were merged with…

Sea Ice Concentration data from AMSR-E, AMSR2 & SSMIS, U Bremen and U Hamburg ASI algorithm
Years of record
- to
The sea ice data derived from AMSR-E using the ARTIST sea ice (ASI) algorithm offer a factor of 4 finer spatial resolution than most sea ice data sets from passive microwave satellite instruments. ASI is based on the difference of vertically and horizontally polarized brightness temperatures at 89 GHz; this difference is independent of temperature but depends…

Sea Ice Concentration data from NASA Goddard and NSIDC based on Bootstrap algorithm
Years of record
- to
Bootstrap sea ice refers to a well-known algorithm used to estimate sea ice concentration from passive microwave brightness temperatures. It can be applied to data from many satellite instruments, such as SMMR, SSMI, and AMSR-E. This page discusses the algorithm itself and the long-term data set ("NSIDC 0079, version 2") produced by J. Comiso and distributed…

Sea Ice Concentration data from NASA Goddard and NSIDC using AMSR-E and NASA TEAM2 (NT2) algorithm
Years of record
- to
The AMSR-E/NASA Team 2 (NT2) data set of Arctic and Antarctic sea ice concentration is available at daily timesteps and 12.5 km (optionally 25km) spatial resolution for 2002-2011. NT2, an extension of the original NASA Team algorithm, uses AMSR-E 89GHz channels to help resolve ambiguity between low ice concentrations and areas with strong surface effects (due…

Sea Ice Concentration data: Overview, Comparison table and graphs
Years of record
- N/A
Sea ice concentration is both an indicator and driver of high-latitude climate change with strong societal and ecological importance. It is a key boundary condition for atmospheric models (including those used in atmospheric reanalyses) and a benchmark for coupled climate models. As such, numerous methods have been developed to estimate sea ice concentration…
