Light Attenuation (Kd(PAR))

This dataset represents monthly and annual averages of percentage light reaching at 1 m depth relative to surface light (KdPAR). The units are in percentage (%) as surface light reaching at 1 m depth derived from raw dataset. Wave band is 400-700 nm or Photosynthetic Active Radiation (PAR). Raw data available monthly from Jan 1, 2010, to Dec 31, 2017, with a spatial resolution of 4 km x 4 km. The monthly and annual means are summarized for the time period 2010-2017. Data provided by NESDIS Center for Satellite Applications and Research (STAR). Raw dataset collected by NASA satellite SUOMI National Polar-orbiting Partnership (NPP) using Visible Infrared Imaging Radiometer (VIIRS). Citation: SeungHyun Son, Menghua Wang., 2015: Diffuse attenuation coefficient of the photosynthetically available radiation Kd(PAR) for global open ocean and coastal waters. Remote Sensing of Environment, Volume 159, 15 March 2015, Pages 250-258.
