Since its initial ensemble forecasts were utilised by a selected number of clients in early 2010, OWS has further developed its suite of global and regional models utilised in its multi-model ensemble forecasts.

OWS ensemble products are now based on wind and wave model outputs derived from five distinct global atmospheric models, including the new ACCESS model developed by the Australian Bureau of Meteorology. In selected areas, OWS now also includes a sixth model, the WRF model run in-house at OWS.

Moreover, all offshore weather forecasts provided to clients by Offshore Weather Services have utilised the ensemble products since August 2010.
