摘要：Although data assimilation in paleoclimatology has shown significant progress, the model data comparison step remains a limiting factor because paleoclimate (proxy) records have generally a complex response to both climatic and nonclimatic factors. In experiments performed in a controlled framework, Dee et al. (2016) have applied proxy system models that simulate tree ring width, isotopic composition of corals and isotopic composition of ice cores from the results of a climate model. The difference between those simulated variables and the value measured on the natural archive can then be computed directly, improving significantly the performance of the data assimilation method.
