What is NOAA-19?
NOAA-19, also known by its NORAD ID 33591, is the last satellite in the Polar Operational Environmental Satellites (POES) series. Launched on 6 February 2009, it serves as a key component in the National Oceanic and Atmospheric Administration's (NOAA) mission to monitor weather patterns and environmental conditions from space. This satellite is part of a long lineage of weather satellites that have provided critical data for weather forecasting and climate research.
Mission and Purpose
The primary mission of NOAA-19 is to collect global data on atmospheric temperature, humidity, cloud cover, and surface temperatures. This information is vital for weather prediction models and climate monitoring. Equipped with instruments like the Advanced Very High Resolution Radiometer (AVHRR) and the High Resolution Infrared Radiation Sounder (HIRS), NOAA-19 continues to support meteorologists and researchers by providing data that enhance our understanding of Earth's weather systems.
Orbital Characteristics
NOAA-19 operates in a sun-synchronous orbit, which allows it to pass over the same part of the Earth at roughly the same local solar time. This orbit is approximately 870 km above the Earth with an inclination of 98.7 degrees. The satellite completes an orbit approximately every 102 minutes. Such an orbit is ideal for consistent lighting conditions, which is crucial for accurate weather monitoring and data collection.
Significance and Legacy
As the final satellite in the POES series, NOAA-19 marks the end of an era in polar orbiting weather satellites. The POES programme has been instrumental in advancing weather forecasting and climate science since its inception in the 1960s. NOAA-19's legacy includes its contribution to improving the accuracy of weather predictions and enhancing our understanding of climate change. The data it provides continue to be used in conjunction with newer satellite systems, ensuring a comprehensive approach to environmental monitoring.
Current Status
NOAA-19 remains operational and continues to transmit valuable data back to Earth. Despite being launched over a decade ago, it still plays a crucial role in global weather observation. Its data can be accessed and analysed through various platforms, including the Orbital Radar Satellite Library, which provides detailed information on its current status and historical performance.
