Remote Sensing Spectroscopy for wetlands BIOdiversity (RESSBIO) project aim is to investigate and exploit the capabilities of new Earth Observation satellite missions, equipped with hyperspectral sensors, in the assessment and monitoring of the ecological status of lentic aquatic systems. The new hyperspectral missions already in orbit (PRISMA and EnMAP) offer the possibility of studying the organic matter and phytoplankton composition, separating groups indicators of ecological status (diatoms, chlorophyceae, cyanobacteria, dinoflagellates), as well as the organic matter composition (dissolved and particulate). During the first months of RESSBIO project, field samplings in Albufera de València and Bellús and Beniarrés reservoirs have been carried out, coinciding with PRISMA images acquisition to obtain in situ radiometry and several limnological variables. First, the atmospheric correction of PRISMA L2D images has been validated in our study area (hypertrophic waters), comparing the image remote sensing reflectance (Rrs) with the in situ Rrs convoluted according to the PRISMA image spectral response functions. On the other hand, with the in situ limnological variables data, the accuracy of some algorithms calibrated and validated in the study area were tested in PRISMA images. The good response regarding the algorithms applied with this pre-test is an indication that our hypothesis was correct, and we can obtain algorithms to distinguish both organic matter and phytoplankton composition with hyperspectral sensors.
