Arctic System Reanalysis (ASR)
Years of Record: 1999/12 to 2012/11
The Arctic System Reanalysis is a multi-agency, university-led retrospective analysis (reanalysis) of the Greater Arctic. ASR is produced using high-resolution versions of the Polar Weather Forecast Model (PWRF) and the WRF-VAR and High Resolution Land Data Assimilation (HRLDAS) data assimilation...

CARINA: Carbon in the North Altantic
Years of Record: 1977/12 to 2006/11
The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and US partners. It has produced a merged internally consistent data set of open ocean subsurface measurements for biogeochemical investigations, in particular...

NSIDC Sea Ice Index
Years of Record: 1978/09 to 2020/12
The NSIDC Sea Ice Index is a suite of easy-to-use sea ice analyses to track changes in Arctic and Antarctic sea ice. The product is produced and supported by the NOAA at NSIDC group and consists of browse imagery and data text files (CSV or Excel format). The input data is from two sources...

Sea Ice Concentration data: Overview, Comparison table and graphs
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...

Sea Ice Thickness Data Sets: Overview & Comparison Table
While satellite observations of sea ice extent and concentration are available from 1979, long-term high quality (daily and high spatial resolution) observations of sea ice thickness remain limited as a result of few satellite and in situ observations. Reconstructions using numerous observational...

Walsh and Chapman Northern Hemisphere Sea Ice
Years of Record: 1869/12 to 2011/11
The Walsh and Chapman Sea Ice Data Set provides a long record of Arctic sea ice concentrations on a monthly basis for 1870-2011. Historical observations were gridded and combined with satellite-derived sea ice concentrations for the recent decades. Mostly climatologies before the 1950s. The Walsh...
