(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 mean grids (~840m), then the daily mean grids are averaged into annual gridded chlorophyll-a.

The individual overpasses are composited into daily mean grids (~840m), then the daily mean grids are averaged into seasonal gridded chlorophyll-a. 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. Seasons represent the periods January to March, April to June, July to September, and October to December.
