NOAA19

NOAA-19, also known as NOAA-N Prime, is the last satellite in the National Oceanic and Atmospheric Administration's Polar-orbiting Operational Environmental Satellite (POES) series. Launched on February 6, 2009, it continues the legacy of providing vital environmental data for weather forecasting and climate monitoring. NOAA-19 operates in a sun-synchronous, near-polar orbit, circling the Earth approximately 14 times a day. This orbit allows it to observe the entire planet's surface at least twice daily, providing consistent coverage.

The satellite carries a suite of advanced instruments designed to measure a variety of atmospheric and surface conditions. Key instruments include the Advanced Very High Resolution Radiometer (AVHRR), which captures visible and infrared imagery for cloud analysis and sea surface temperature determination, and the High Resolution Infrared Sounder (HIRS), which measures vertical temperature and moisture profiles in the atmosphere. Other sensors onboard NOAA-19 contribute to data on atmospheric ozone, atmospheric radiation, and space weather. The data collected by NOAA-19 is crucial for numerical weather prediction models, enabling more accurate forecasts of severe weather events, hurricanes, and other meteorological phenomena. It also plays a significant role in long-term climate studies, tracking changes in global temperatures, ice cover, and sea levels. As the final satellite in the POES series, NOAA-19 represents the culmination of decades of polar-orbiting satellite technology, providing a robust foundation for ongoing environmental observation efforts. Its mission has been extended beyond its design life, demonstrating its continued utility and reliability.
