COSMIC-2 Benefits

 

The Science

COSMIC-2 data can be collected in all weather conditions over land and sea. The radio occultation technique gives scientists a near real-time snapshot of atmospheric conditions, including:

  • Temperature
  • Air pressure
  • Density
  • Water vapor content (humidity)

These data are important for computer models used in medium and long-range weather forecasts.

What that means

  • Global tropical data coverage
    At a 24-degree inclination, the COSMIC-2 constellation will take frequent measurements of the region where tropical storms form.
  • Improved weather forecast models
    COSMIC-2 observations are expected to improve the accuracy of weather forecast models.
  • High-resolution water vapor data
    This new data will help meteorologists better observe, research and forecast hurricanes, typhoons and other storms.
  • Space-weather monitoring
    The ability to monitor the effects of solar flares and other space weather will increase lead time for detecting events that could put our electric grids at risk.
  • Global temperature and climate monitoring
    Highly accurate tropical temperature reading will help us better understand long-term variations in Earth’s climate. COSMIC-2 data can also be used to test and improve climate models.
