| attribute | NC_GLOBAL | summary | String | 7-day median chlorophyll-a concentration for the U.S. East Coast from the VIIRS instrument aboard the S-NPP satellite, 2012-present, is produced using the blue-green reflectance ratio empirical approach of O'Reilly et al. (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 7-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. More info: https://eastcoast.coastwatch.noaa.gov/cw_viirs_chl.php |
