Recently various global ocean surface heat flux products are provided for global climate studies. Those products include three kinds of data sets. e.g., reanalysis data, satellite-derived data and in situ data. In this study we estimate global oceanic meridional heat transports using surface energy balance method. We mainly use J-OFURO2 surface heat flux data set which is recently released and considerably improved compared with the previous version. For example, the sampling error can be reduced by using many sensors for estimation of one meteorological variable. Also the time resolution is changed from three days to one day. Moreover, we estimate meridional heat transports using other data such as other satellite-derived products and reanalysis products and comare the results with each other and the results by in situ observational results obtained by WOCE etc.
