Scientists are closely monitoring the return of El Niño conditions as warming sea-surface temperatures in the tropical Pacific begin influencing weather patterns around the world. New satellite observations provide an increasingly detailed view of changes occurring across the Pacific Ocean, offering researchers valuable information for seasonal forecasting.  Earth-observation satellites measure sea-surface temperatures, cloud development, rainfall

New observations from NASA’s TEMPO mission are providing an unprecedented look at how air pollution changes throughout the day across the northeastern United States. Recent imagery captured elevated ozone concentrations stretching from New York City to Washington, D.C., demonstrating the ability of the instrument to track atmospheric conditions with remarkable detail.  Unlike previous satellite missions

A new suite of geospatial innovations designed to turn data into actionable intelligence for global food systems was announced on May 27, 2026. The Geospatial Innovation for Food Security (GIFS) Challenge selected three project awardees to develop tools that will aid humanitarian agencies, governments and agricultural specialists to navigate the complexities of agricultural production, climate

Maps can show more than just where things are—they can also show how things change. New maps of artificial light reveal a planet that has been reshaping its nights through patterns of brightening and dimming.  The maps are based on a recent analysis of NASA’s Black Marble data, which found that instead of a gradual increase in
