  "abstract": "<p>Lake water quality monitoring has the potential to be improved through integrating<br>\ndetailed spatial information from new generation remote sensing satellites with high frequency<br>\nobservations from in situ optical sensors (WISPstation). We applied this approach for Lake Trasimeno<br>\nwith the aim of increasing knowledge of phytoplankton dynamics at dierent temporal and spatial<br>\nscales. High frequency chlorophyll-a data from the WISPstation was modeled using non-parametric<br>\nmultiplicative regression. The &lsquo;day of year&rsquo; was the most important factor, reflecting the seasonal<br>\nprogression of a phytoplankton bloom from July to September. In addition, weather factors such as<br>\nthe east&ndash;west wind component were also significant in predicting phytoplankton seasonal and diurnal<br>\npatterns. Sentinel 3-OLCI and Sentinel 2-MSI satellites delivered 42 images in 2018 that successfully<br>\nmapped the spatial and seasonal change in chlorophyll-a. The potential influence of localized inflows<br>\nin contributing to increased chlorophyll-a in mid-summer was visualized. The satellite data also<br>\nallowed an estimation of quality status at a much finer scale than traditional manual methods. Good<br>\ncorrespondence was found with manually collected field data but more significantly, the greatly<br>\nincreased spatial and temporal resolution provided by satellite and WISPstation sensors clearly oers<br>\nan unprecedented resource in the research and management of aquatic resources.</p>",
