Analysis Of High Frequency Hyperspectral Remote Sensing Reflectances From Autonomous In Situ Sensors Deployed In Lakes

The complex aquatic ecosystems, such as lakes, are characterized by a high level of hourly and daily dynamic due to the rapid growth / decrease of phytoplankton, and to the variation of the total Suspended Solids due for example to the re-suspension of the bottom caused by winds. To this variability is added the variability also the spatial one. Satellite images have the advantage of being able to respond well to the understanding of spatial variability and temporal variability during the days but not able to explore the hourly temporal variability. For this reason, within the H2020 - EOMORES project we are integrating the use of water quality products obtained from Sentinel-2 and Sentinel-3 images with Remote Sensing Reflectance (Rrs) measurements obtained from spectroradiometers mounted on platforms and / or on floating buoys that allow continuous measurements during the day and for several consecutive days.
