Harmful algal bloom data from NASA range from citizen scientist observations to high-resolution imagery from space. Our datasets and tools help users find and integrate the data they need to detect and forecast dangerous algal blooms.
Delivery of Suomi National Polar-orbiting Partnership (Suomi NPP) satellite data products will cease on November 1, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.
