C-HARM v2 Nowcast, Pseudo-nitzschia, cellular domoic acid, and particular domoic acid probability, California and Southern Oregon coast, 2022-present

The C-HARM model generates nowcast and forecasts of the probability of Pseudo-nitzschia concentrations of in excess of 10,000 cells/L, the probability of particulate domoic acid > 500 nanograms/L, and the probability of cellular domoic acid > 10 picograms/cell in California and Southern Oregon coastal water. Inputs for the model include near real-time satellite observations gap-filled chlorophyll a, 486nm reflectance, and 551nm reflectance fields from the S-NPP NOAA VIIRS sensor plus nowcast and forecast data of surface salinity, sea surface temperature, and surface currents from WCOFS ROMS. The chlorophyll a, reflectance, temperature, and surface current fields are included in the dataset

history=2022-12-02: DINEOF gap filling was applied to daily S-NPP NOAA VIIRS chlorophyll, 551nm reflectance, and 486nm reflectance fields extending back 180 days from today's date.
The gap-filled data plus salinity and temperature data from the CA-ROMS 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 ROMS forecast data were used as inputs to the C-HARM model to obtain forecasts for 1, 2, and 3 days into the future.
