Both models are used in the Copernicus Marine Service. In the future, we will connect neXtSIM with TOPAZ so that we can offer a combined forecasting system that brings together the best features of the two systems. Alongside the regular forecasts available through the Copernicus Marine Service, we can provide more detailed forecasts for specific areas as required.<\/p>\n<p>[\/vc_column_text]<div class=\"infobox teal\">\n<p style=\"text-align: center;\">For more information, contact <a href=\"https:\/\/nersc.no\/en\/ansatt\/einar-olason\/\"><strong>research leader Einar \u00d3lason<\/strong><\/a>.<\/p>\n<\/div>[\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][\/vc_section]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_section css=&#8221;.vc_custom_1669014075681{background-color: #ffffff !important;}&#8221; el_class=&#8221;full-image&#8221;][vc_row][vc_column][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;2\/3&#8243;][vc_column_text] TOPAZ covers large ocean areas while neXtSIM is a sea-ice model that uses advanced methods to simulate important processes such as breaking up of ice and the transition zone between dense sea ice and open water.
