UHH Sea Ice Area Product

DOI

Abstract: This data set comprises time series of the monthly sea-ice area (SIA) in the Northern Hemisphere (1 file) and in the Southern Hemisphere (1 file). SIA is derived from sea-ice concentration (SIC, also sea-ice area fraction) data of the following products: Walsh (version 2, only Northern Hemisphere), OSI-450 / OSI-430-b, HadISST (version 2), NASA-Team and Comiso-Bootstrap - both from the NSIDC/NOAA SIC climate data record (version 3.1). The monthly SIA is either directly computed from monthly SIC data or is derived as the mean of all daily SIA values. If required, the observational gap at the pole is interpolated. If required, temporal interpolation is applied - both to fill temporal (up to a maximum of 7 consecutive days) and spatial (if less than 1000 non-contiguous missing grid cells per day) gaps.
