(1998), adjusting the algorithm for the VIIRS spectral bands. Specifically, the algorithm is a 3-band algorithm (OC3V) whose inputs are the water-leaving radiance at wavelengths of 443, 486, and 551 nm (NOAA VIIRS ATBD, 2017). Atmospheric correction uses the near-infrared (NIR) approach of Jiang and Wang (2014), referred to as the BMW atmospheric correction. The individual overpasses are composited into daily grids (~840m), then the median 3-day gridded chlorophyll-a is calculated from the daily grids. Data in the last year of the series represent near real-time data and are of lesser accuracy than the science-quality data of the years before the last year. Updates from near real-time to science-quality may occur more frequently than yearly.
