Published by Office for Coastal Management | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 19, 2025 | Last Modified: 2024-08-15T14:01:53.000+00:00
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).
