❓ Frequently Asked Questions
What is nowcasting?
Nowcasting is short-term weather forecasting (typically 0–6 hours ahead) using real-time observations to predict imminent conditions such as rain or storms.
What are next-generation radar and satellite constellations?
They are upgraded networks of ground-based radar and fleets of satellites in various orbits that provide high-resolution, frequent observations for near real-time weather monitoring.
How do radar and satellite data work together for nowcasting?
Radar measures precipitation intensity and movement; satellites monitor cloud cover, temperature, and humidity. Combined, they give a timely, detailed view of evolving weather.
Why is this important for natural disasters in the United States?
Real-time, precise data enables faster warnings and better decision-making to protect lives and property during severe weather events like storms, floods, and tornadoes.
