The video discusses the importance of measuring rain for various aspects of life, such as safety and economy. It highlights the limitations of traditional rain gauges and radar technology, which only cover small areas and are not available everywhere. The video introduces the Global Precipitation Measurement Mission (GPM), which uses satellites to provide comprehensive global precipitation data every three hours, covering land, oceans, and various terrains.
