In this paper, publised in JGR Oceans recently,  Carolina, together with other collegues at NIOZ Yerseke,  looked at how the use of different temperature and salinity data sets can be one of the causes of the different estimates of steric sea‐level change published so far. They also investigated how different methods (noise models) used to obtain the rate of change can be another source of different results. They found that the rate of change can vary up to 2 mm/year for the global mean as a result of different data sets and methods used. Regionally, differences can reach up to several tens of millimeters per year. They show that the noise models should always be carefully chosen for each region, so that the rate of change is accurately estimated.
