The J-SCOPE forecast system for Washington and Oregon coastal waters forecasts sea-surface temperature (SST), chlorophyll stock, dissolved oxygen, and sardine habitat. The forecasts are composed of three ensemble members each relying on complementary forcing files from CFS. Forecasts are reported as anomalies - in other words, the forecasted fields differenced from a climatology, in order to provide context as to how "characteristic" the forecasted conditions are expected to be. For more information about anomalies, please see the NANOOS Climatology App. This climatology consists of an average of forecasted conditions from either the January or April initialized forecasts spanning 2009 to 2017 (N = 12 runs for each climatology). The reforecast climatology shown on this page will be used as the reference fields for the forecasted anomalies for all forecasts from 2018 onward. January initialized forecasts will use the January initialized reforecast climatology.
