The Atmospheric Infrared Sounder (AIRS)

The Atmospheric Infrared Sounder (AIRS) is a sophisticated instrument aboard NASA's Aqua satellite that measures Earth's atmospheric temperature, humidity, and cloud cover using infrared radiation. By capturing detailed data on these conditions, AIRS helps meteorologists improve weather forecasts and track climate changes. It essentially "listens" to the infrared signals emitted by Earth's atmosphere, allowing scientists to analyze weather patterns and atmospheric composition from space with high accuracy and resolution.
