C-HARM v1 2-Day Forecast, Pseudo-nitzschia, cellular domoic acid, and particular domoic acid probability, California and Southern Oregon coast, 2018-2022

Published by NOAA NMFS SWFSC Environmental Research Division | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-03-18T00:00:00.000+00:00
The C-HARM model generates nowcast and forecasts of the probability of Pseudo-nitzschia concentrations of in excess of 10,000 cells/L in California and Southern Oregon coastal water. Gap-filled chlorophyll a, 488nm reflectance, and 555nm reflectance fields are included in the dataset. Inputs for the model include near real-time satellite observations of ocean color and Regional Ocean Modeling System (ROMS) model nowcast and forecast of surface salinity, sea surface temperature, and surface currents
