An accurate knowledge of the ocean has a profound impact on our ability to forecast the weather over a variety of timescales, from just a few days out to many months. Energy is constantly being exchanged between the atmosphere and the ocean, and our coupled model, which includes the ocean model NEMO (Nucleus for European Modelling of the Ocean) in the Integrated Forecasting System (IFS), aims to capture these highly complex interactions. The ocean surface is clearly critical as it is where these physical interactions take place. In particular, the sea-surface temperature (SST) needs to be determined extremely accurately to make successful forecasts. Here we describe a new way of determining SST from coupled data assimilation.?</p>
