Bi or quarterly monitoring at some sampling stations provides relevant water quality (WQ) management information on the watershed scale. However, it does not provide enough spatial coverage and temporal frequency to support effective public policies for the sustainable use of local aquatic systems. Due to the high variability in the optical properties of aquatic systems, the monitoring frequency should allow for continuous tracking of WQ temporal dynamics, enabling regulatory agencies to issue alerts to managers when necessary. Despite the availability of orbital optical sensor constellations for systematic remote sensing of aquatic systems, there is currently no platform for continuous and automated WQ monitoring. This paper introduces the prototype of the MAPAQUALI platform, a modular continuous monitoring platform that integrates three aquatic systems.
