The gap-filled data plus salinity and temperature data from the WCOFS model were used as inputs to the C-HARM model to obtain nowcast. ROMS current forecasts were used to advect the NOAA VIIRS data 1, 2, and 3 days into the future. Data gaps resulting from the advection were filled with a second DINEOF. The advected gap-filled data plus salinity and temperature WCOFS forecast data were used as inputs to the C-HARM model to obtain forecasts for 1, 2, and 3 days into the future.
