This module is an introduction to NOAA's next-generation Geostationary Operational Environmental Satellite-R (GOES-R) series, focusing on the value and anticipated benefits derived from an enhanced suite of instruments for improved monitoring of meteorological, environmental, climate, and space weather phenomena and related hazards. An extensive set of visualizations highlight GOES-R and its advanced observing capabilities for providing support in thirteen key environmental application areas including air quality and visibility, climate, cloud icing, fires, hurricanes, land cover, lightning, low clouds and fog, marine and coastal environments, precipitation and flooding, severe thunderstorms, space weather, and volcanoes. The module includes an overview of the GOES-R space and ground infrastructure, highlighting key elements and services of the GOES-R program. In addition, the module reviews and contrasts basic concepts and capabilities applicable to geostationary and polar-orbiting satellites, exploring the complementary nature of the two systems. This feature was created by the COMET Program and provided to the National Science Digital Library (NSDL).
