Low-Earth-orbiting (LEO) meteorological satellite constellations, operated by international weather agencies such as the National Oceanic and Atmospheric Administration (NOAA) in the United States and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), provide critical weather and environmental observations. These data are made freely available to the public through interagency collaboration, coordination, and standardization efforts led by the World Meteorological Organization (WMO). The goal is to ensure effective and timely utilization of these data for weather monitoring and maintaining climate records. The satellite-based direct broadcast system (DBS), established in the early 1970s, is a product of these historical and ongoing international efforts. DBS enables continuous access to satellite observations without political restrictions. This study explores the use of NOAA Joint Polar Satellite System (JPSS) and EUMETSAT's MetOp satellite series, highlighting their contributions to regional weather and environmental monitoring. We demonstrate how these assets, combined with DBS technology, NOAA Community Satellite Processing Package (CSPP), and sustained operational and educational efforts, support weather forecasting and environmental monitoring. The study reviews the NOAA JPSS and EUMETSAT MetOp LEO sensors, observations, and DBS systems. It also highlights unique regional applications in the greater Shanghai area, showcasing how this end-to-end infrastructure can prepare society and commerce for the lasting impacts of extreme weather and environmental changes.</div>
