Background Information
Background information from the source
information
originator
Annual average diffuse attenuation coefficient at 490nm (Kd490) for the U.S. East Coast, from the VIIRS instrument aboard the S-NPP satellite, 2012-present, is produced using the Wang et al. (2009) algorithm, in which separate algorithms for clear open ocean and turbid coastal waters are weighted into a combined product. This approach improves accuracy across ocean conditions. 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.
