Model type II regression for lagrangian validation of HF radar velocities in the NW Iberian Peninsula

Two designs of lagrangian low-cost drifting buoys have been developed in order to monitor the ocean surface dynamics in the North-west Iberian Peninsula and provide ground-truth observations that can be used to assess the performance of High Frequency (HF) Radars of RAIA observatory from 2020 to 2022. Since regression model type I, which is typically used in buoy-HF radar antennas validations, does not consider the presence of errors in the observations from both instruments, regression model type II was proposed to instrument intercomparison. Furthermore, a new metric was developed to better assess both model types regressions in lagrangian validations.Peer Reviewe

A window to the sea: RAIA observatory tool for assessing environmental risks in the NW Iberian coastal upwelling system

The international RAIA Observatory serves the main maritime activities of the NW Iberian coastal upwelling system. Over the last few years, the partners of the observatory have identified at least 12 key environmental risks that can potentially affect the ecosystem services of this coastal area. In order to evaluate these risks, different environmental indicators are used, which are developed and optimized according to the specifications provided by international environmental agencies. A Window to the Sea is the publicly-accessible web-service created to present and share the results from this evaluation. So far, current results have allowed to establish risk assessment protocols for the coastal region, and identify critical observational gaps. The web-is user-friendly with the intention to achieve as many end-users as possible, not only from academia, but also from other governmental institutions, fisheries, enterprises and the general public.Peer Reviewe
