Wednesday, December 5, 2018. 3:00PM. Webinar: New technology support for remote sensing of lake water quality using automated field radiometers. Timothy S. Moore, Ocean Process Analysis Laboratory. Sponsored by NOAA. More information here.

In the summer of 2016, a robotic sun photometer called the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) Photometer Revision for Incident Surface Measurements (SeaPRISM), was deployed at a Coast Guard channel marker in western Lake Erie, measuring atmospheric properties and spectral water-leaving radiance. The instrument was deployed by the National Oceanic and Atmospheric Administration (NOAA) to support remote sensing validation and harmful algal bloom (HAB) satellite products. The Lake Erie SeaPRISM is also part of the international federated AERONET program maintained by the National Aeronautics and Space Administration (NASA), and more specifically is part of the AERONET Ocean Color (AERNOET-OC) network. The main purpose of this component of AERONET is specific to calibration/validation efforts for ocean color. In the summer of 2017, a new 12-channel version was deployed at the same site with additional channels in the red and near-infrared. This unit is the first ‘lake' version of the SeaPRISM. In this webinar, the data collected by the SeaPRISM at this site over the last three years (2016-2018) will be examined in the context of HABs and remote sensing validation. The SeaPRISM observations in relation to remote sensing validation and on cyanobacteria blooms from hourly to weekly time scales will be highlighted in this presentation.
