Environmental monitoring is essential in enhancing our understanding of natural ecosystems functioning, addressing effective responses to the challenges posed by climate change, pollution and biodiversity loss. The Internet of Things technology (IoT) has significantly improved observing capabilities, enabling continuous and real-time data collection, even from remote locations, thereby extending the spatial and temporal coverage of environmental monitoring systems. A major challenge still lies in acquiring in situ optical data, which are essential for improving assessments of primary production rates as well as of marine food web dynamics, carbon cycling processes and ecosystem resilience.
Featuring high-quality components, modularity and low power consumption, Tetraspec technology, developed by Nature 4.0, is a 28-channels spectrometer that operates over a range of 410 nm to 940 nm and includes measurements of Photosynthetically Active Radiation (PAR) and Near-Infrared (NIR). Tetraspec is a low-cost, portable and accurate system capable of acquiring a great amount of data for remote sensing and numerical models validation, being easily integrated with various acquisition systems.
This work presents the results of the Tetraspec's laboratory and in situ calibration, detailing its optical characteristics, operational capabilities and applications in both terrestrial and marine environments, through the comparison with reference standard instruments.
