    • KdPAR and surface water-quality data collected in the Sacramento-San Joaquin River Delta in 2013 and 2014

    Metadata Updated: October 29, 2025

    Data release provides diffuse light attenuation coefficient of photosynthetically active radiation (KdPAR) derived from in-situ light measurements, along with surface water-quality and atmospheric data collected in the Sacramento-San Joaquin Rive Delta in California between January 2013 and May 2014. These associated surface level water-quality and atmospheric data, and categorical variables (for example season, region, etc.) were used to develop a KdPAR model using in situ light profile data collected in tandem, which we derived KdPAR from.
