Freshwater flux product reconstruction based on Argo data and mixed layer model
基于Argo资料和混合层模式的淡水通量产品重构

Sea surface freshwater flux(FWF, evaporation minus precipitation) plays an important role in understanding and modeling atmosphere and ocean processes, but there exists strong disagreement different freshwater flux estimates. In this study, a weekly sea surface FWF product is reconstructed for the period from 2002 through 2008 based on the mixed layer salinity balance model for the first time, by combining the Argo data with OSCAR current data. Compared with the other precipitation and evaporation data from satellite product and TAO observations, the reconstructed FWF can capture not only the seasonal cycle of freshwater flux, but also some high-frequency features of freshwater flux. The FWF product provides a useful tool for studying the climate variation over the ocean.
