Can we reconstruct Arctic sea ice back to 1900 with a hybrid approach?
(2008)Climate of the Past DiscussionsThe variability and trend of Arctic sea ice since the mid 1970s is well documented and linked to rising temperatures. However, much less is known for the first half of the 20th century, when the Arctic also underwent a period of strong warming. For studying this period in atmospheric models, gridded sea ice data are needed as boundary conditions. Current data sets (e.g., HadISST) provide a historical climatology, but may not be suitable ...Working Paper
