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

Metadata Updated: June 10, 2023

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

Lineage 2022-03-18: DINEOF gap filling was applied to daily MODIS Aqua chlorophyll, 555nm reflectance, and 488nm reflectance fields extending back 180 days from today's date. The gap-filled data plus salinity and temperature ROMS data were used as inputs to the C-HARM model to obtain nowcast. ROMS current forecasts were used to advect the MODIS data 1, 2, and three days into the future and gap-filled with DINEOF. These gap-filled data plus salinity and temperature ROMS forecast data were used as inputs to the C-HARM model to obtain forecasts for 1, 2, and 3 days into the future.
