Global NOAA CoastWatch Chlorophyll Frontal Product from MODIS/Aqua (NODC Accession 0110333)

MODIS/Aqua chlorophyll frontal products: the NOAA Okeanos operational production system produces near real-time chlorophyll frontal products (magnitude and direction), with data of MODIS/Aqua L2 chlorophyll products that are generated in the Okeanos system using the NASA L2gen ocean color algorithm. The chlorophyll frontal products are calculated using the BOA-SNRA which is a concatenation of two acronyms, BOA and SNRA. The BOA stands for the Belkin-O.Reilly Algorithm for front detection (Belkin and O.Reilly, 2009) and the SNRA stands for the Stripe Noise Reduction Algorithm (Belkin et al, 2013). The BOA-SNRA code is included in the CoastWatch ocean color products processing software that was written by the NOAA CoastWatch team. Maps of oceanic chlorophyll fronts can be directly used in marine fisheries, marine conservation, environment protection, and other applications and operations. Real-time chlorophyll frontal products can be accessible via the following URL address: ftp://cw-okeanos.noaa.gov/pub/data1/products_by_type/aqua/frontal/. The historical products are archived in the NOAA Comprehensive Large Array-data Stewardship System (CLASS).
