Which non-military application is commonly associated with infrared technology?

• A. Weather forecasting
• B. Target acquisition
• C. Night vision
• D. Hearing

Answer: (A)

Infrared technology measures heat emitted by objects, and weather forecasting relies on that thermal information. Satellites equipped with infrared sensors detect the temperature of cloud tops, land, and sea surfaces, producing thermal imagery that reveals temperature patterns across the atmosphere. These patterns help meteorologists track storm development, estimate cloud heights, and infer atmospheric temperatures even when it’s cloudy or dark. That civilian, widespread use—providing essential weather data without needing daylight—makes weather forecasting a classic non-military application of infrared. Night vision and target acquisition are more tied to military uses, while hearing isn’t related to infrared at all.
