AI Sharpens Rainfall Estimates from Satellites

Weather satellites provide an invaluable service to society, allowing us to monitor weather patterns and predict extreme weather events. They can detect storms such as hurricanes, tornadoes, and floods before they occur, giving people time to evacuate and prepare for the worst. Weather satellites are also able to track snowfall, measure sea levels, and observe changes in the earth's climate over time.

The first weather satellite was launched in 1960, and since then, more than 100 of them have been placed in orbit. Each satellite is equipped with a variety of instruments that measure different aspects of the atmosphere. This data is sent back to Earth and analyzed by meteorologists, who then use it to create detailed weather forecasts.

Today, weather satellites are becoming increasingly complex and powerful. For example, the GOES-R series of satellites can generate images of the entire Earth every 15 minutes. These images are used to better understand the dynamics of hurricanes, and how they evolve as they move across the ocean.

Another type of weather satellite is called Synthetic Aperture Radar (SAR). These satellites use radar waves to generate images of the Earth's surface, giving us information about how the land is changing over time. For example, SAR images can be used to study coastal erosion or the extent of flooding after natural disasters.

In addition to these functions, some weather satellites are used to collect data on air quality. These satellites measure air pollution levels, helping researchers identify sources of pollution and track their movement around the globe. By doing so, they are able to alert local authorities to take action in order to improve air quality in areas where it is poor.

Weather satellites play a crucial role in keeping us safe and informed. They help us prepare for extreme weather events, study climate change, and even help protect air quality. Without these satellites, our lives would be very different.
