Numerous published models exist in the Gulf, along with many ongoing efforts aimed at enhancing our understanding of the complex hydrodynamics of the Gulf of America. These models are often disseminated through journals, white papers, presentations, and outputs presented as matrices of generated data. While they are invaluable to some researchers and scientists, visualizing water flows and other matrices of environmental parameters remains a significant challenge. Visualizing the model's output in seconds, is crucial for making informed decisions, especially during time-sensitive operations.

To address this need, the Gulf of America Coastal Ocean Observing System [GCOOS) has introduced a user-interactive tool for model visualization known as the GCOOS Regional Model Handler/Viewer (https://modelhandler.gcoos.org/), developed at the Harte Research Institute, Texas A&M University-Corpus Christi.

By integrating actual data observations, the models can be validated, calibrated, and assessed for their performance. Crucially, visualization tools enable effective communication with stakeholders. This paper presents the GCOOS Regional Model Handler/Viewer, discusses the impact of visualizing complex regional models, and outlines the approach taken to develop the tool.
