摘要: We present a new version of the sea ice concentration component Met Office Hadley Centre and surface temperature data set, HadISST.2.1.0.0. Passive microwave are combined with historical sources, such as charts, to create global analyses on 1° grid from 1850 2007. Climatology was used when no information about available. Our main aim homogenous set by calculating applying bias adjustments using periods overlaps between different sources used. National Ice Center charts 1995 2007 have been reference achieve this. In particular, large applied passive in both Antarctic Arctic summers. Overall, HadISST.2.1.0.0 contains more than HadISST1.1, higher concentrations, shorter marginal zones, larger extents areas some regions periods. A method for estimating concentrations within pack distance edge has developed evaluated. This only were known or original fields heterogeneous. number discontinuities HadISST1.1 record longer found
