GPM Microwave Imager

The GPM Microwave Imager (GMI) is a sophisticated satellite instrument that measures rainfall and snowfall worldwide. Using microwave signals, it can penetrate clouds to detect liquid and solid precipitation, providing accurate data regardless of weather conditions or daylight. This information helps meteorologists understand storm development, monitor climate patterns, and improve weather forecasts. The GMI is part of NASA’s Global Precipitation Measurement mission, which aims to create a comprehensive picture of Earth's water cycle. Its technology allows for detailed, real-time observation of precipitation from space, enhancing our understanding of weather and climate systems globally.
