The climatological forcing includes the boundary conditions at the open boundary (temperature, salinity, current speeds and water elevations), the atmospheric forcing over the whole model domain and the freshwater river input along the coastline. This means that the 1 year model output represents average <em>present </em>day conditions. This kind of output is incredibly useful to a number of stakeholders who are interested in decadal scale conditions rather than any one particular year. The wider SSM has also been run for a future climatology representing conditions averaged over 2023-2062, using predictions from an RCP8.5 climate change scenario. Such work has enabled us to consider how flow/transport around Scotland may change as a result of predicted climate change (see SSM applications section on MRE).</p> full_html<h3>Climatological model runs</h3> <p>The majoring of the models within the SSM framework have been forced using 1 year climatological forcing representing the 25 year period 1990-2014.
