This is a NASA illustration of the Jason-3, launched into orbit in January 2016. Measuring sea surface heights is a primary mission of the new satellite.

Ground Truth: Real-time tide station readings validate sea surface height measurements made from space.

Fourteen of 20 hurricane-force wind events underwent bombogenesis in the North Atlantic during the first two months of 2014. This unusual activity can be seen in wind speed data from the period. In this image, blues indicate areas with wind speeds that are faster than the 30-year historical average (1981-2010).
What is a bombogenesis?

Bombogenesis, a popular term used by meteorologists, occurs when a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours. The formation of this rapidly strengtheining weather system creates what is known as a bomb cyclone.

Coastal Resilience

Resilience is the ability to adapt to changing conditions and withstand—and rapidly recover from—disruption due to emergencies. At NOS, we focus on coastal and ocean resilience. Communities that live near our coasts are increasingly vulnerable to disasters while facing other long-term environmental changes.

Sea Level Rise Module

Attention educators! Check out our sea level rise module and video for students (grades 6 through 12), developed by NOS and NASA's Jet Propulsion Laboratory. This module informs about sea level rise, its causes, and impacts; and challenges students to think about what they can do in response.
