Monterey Bay Experiment Plan: Monterey Bay Experiment Plan COAST


Monterey Experiment to Collect Simulated HES-CW data : Monterey Experiment to Collect Simulated HES-CW data There are no existing data sets that include all the key attributes of HES-CW data: Spectral coverage (.38 – 1.0 mm) High signal-to-noise ratio (>300:1 prefer >900:1, for ocean radiances for 300 m binned data) High spatial resolution (<150 m, bin to 300 m) Hourly or better revisit Propose field experiments in FY2006-2008 to develop the required data sets for HES-CW algorithm and model development. Airborne system: Hyperspectral imager that can be binned to the HES-CW bands Flown at high altitude for minimum of 10 km swath Endurance to collect repeat flight lines every half hour for up to 6 hours SAMSON Proposed experimental site: August-September 2006 Monterey Bay (coastal upwelling, HABs)


Monterey Experiment to collect simulated HES-CW data : Monterey Experiment to collect simulated HES-CW data Experimental Design Choose sites with IOOS or other long term monitoring and modeling activities Intensive effort for 2 weeks to assure that all essential parameters are measured: Supplement standard measurements at the site with shipboard or mooring measurements of water-leaving radiance, optical properties and products expected from HES-CW algorithms, Additional atmospheric measurements as needed to validate atmospheric correction parameters, As needed, enhance modeling efforts to include bio-optical models that will utilize HES-CW data. Aircraft overflights for at least three clear days and one partially cloudy day (to evaluate cloud clearing) during the two week period. High altitude to include 90% or more of the atmosphere 30 min repeat flight lines for up to 6 hours to provide a time series for models and to evaluate changes with time of day (illumination, phytoplankton physiology, etc.) All data to be processed and then distributed over the Web for all users to test and evaluate algorithms and models.
