One use of satellites that affects everyday life is gathering weather data. Satellites equipped with weather monitoring instruments can provide valuable information about the Earth's atmosphere, such as temperature, humidity, wind patterns, and cloud cover. This data is used by meteorologists to forecast weather conditions and issue warnings for severe weather events like hurricanes, storms, and tornadoes. The accurate and timely weather forecasts made possible by satellites help people plan their daily activities, make informed decisions, and stay safe.
