SINALMET is a digital signage solution developed by SIMEPAR in Brazil to disseminate weather, hydrology and environmental information on large displays. It is a web-based platform that runs entirely in the browser using HTML5 and does not require dedicated hardware. It was developed to address the technical problems and high costs of their initial digital signage approach. SINALMET assimilates data from their network of weather stations, radars, lightning detectors and satellites to generate forecast and warning products for display. It provides a low-cost and scalable solution for disseminating their monitoring data.
