Weather satellites are primarily used to monitor the Earth's weather and climate. They have significantly advanced the study of meteorology by providing a broad perspective on weather patterns and real-time data for previously inaccessible areas. Satellites observe both the visible and infrared portions of the spectrum. Radiometers on these satellites detect electromagnetic energy reflected or emitted by the Earth. Two common radiometry methods include:

  • Measuring the amount of visible light from the Sun reflected back to space by the Earth's surface or clouds.
  • Measuring the amount of infrared radiation (IR) emitted by objects.

Satellite images offer a comprehensive view of cloud formations, their extent, and movement, aiding in the identification of weather fronts, storm systems, and potential areas of precipitation.
