SST was biased high throughout the summer for the 2015 April forecast compared to the observations at the OCNMS Cape Elizabeth mooring; in August the forecast was approximately 8 deg C too warm. The January forecast was ~2-3 deg C warmer than the observations in July and August, but forecasted the SST very well in July. Forecasted bottom temperatures were also biased warm by 1-2 deg C at the same mooring.

Sea surface temperature forecasts (top) and bottom temperature forecasts (bottom) compared to the Cape Elizabeth 42-meter station observations. from the OCNMS on the Washington shelf. The modeled fields (January forecast - teal, April forecast - darker blue) were extracted from the model from the same location as the observations (red).
