Arctic sea ice concentration, thickness, and volume dataset from CICE5/DART for 20 years

This dataset consists of sea ice concentration (SIC), sea ice thickness (SIT), and sea ice volume (SIV) data over the Arctic Ocean, obtained from satellite-derived sea ice data assimilation experiments for 20 years (May 1994 - April 2014). The sea ice model and data assimilation system used for this dataset were Los Alamos Sea Ice Model version 5.1.2 (CICE5) and Data Assimilation Research Testbed (DART), respectively. The CICE5/DART experiments were conducted: (1) 'noDA' - experiment without data assimilation, (2) 'SICSITDA' - experiment with both satellite-derived SIC and PIOMAS SIT assimilation. Descriptions of the variables are provided below. Variable Long Name Unit Dimension LAT latitude degrees_north_from_50N [1-d latitude] LON longitude degrees_east_from_0E [1-d longitude] TIME time days since 1994-05-01 [time] ENS number of ensemble member - [1-d range from 1 to 30] SIC sea ice concentration - [number of ensemble member, time, 1-d latitude+longitude] SIT sea ice thickness m [number of ensemble member, time, 1-d latitude+longitude] SIV sea ice volume km^3 [number of ensemble member, time, 1-d latitude+longitude]
