The shrinking Arctic sea-ice area(SIA) in recent decades is a striking m.nifestation of the ongoing clim.te *** of the Arctic sea ice have been continuously observed by satellites since 1979, relatively well m.nitored since the 1950s, but are highly uncertain in the earlier period due to a lack of observations. Several reconstructions of the historical gridded sea-ice concentration(SIC) data were recently presented based on synthesized regional sea-ice observations or by applying a hybrid m.del–em.irical approach. Here, we present an SIC reconstruction for the period1901–2019 based on established co-variability between SIC and surface air tem.erature, sea surface tem.erature, and sea level pressure patterns. The reconstructed sea-ice data for m.rch and Septem.er are com.ared to the frequently used Had ISST1.1 and SIBT1850 datasets. Our reconstruction shows a large decrease in SIA from.the 1920 to 1940 concurrent with the Early 20th Century Warm.ng event in the Arctic. Such a negative SIA anom.ly is absent in Had ISST1.1 data. The am.litude of the SIA anom.ly reaches about 0.8 m.n km.(2) in m.rch and 1.5 m.n km.(2) in Septem.er. The anom.ly is about three tim.s stronger than that in the SIBT1850 dataset. The larger decrease in SIA in Septem.er is largely due to the stronger SIC reduction in the western sector of the Arctic Ocean in the 70°–80°N latitudinal zone. Our reconstruction provides gridded m.nthly data that can be used as boundary conditions for atm.spheric reanalyses and m.del experim.nts to study the Arctic clim.te for the first half of the 20th century.
