Altimetry satellites including Sentinel-6A/Michael Frelich have measured the water level at Lake Kariba—the world’s largest reservoir and a major source of electricity in Zimbabwe and Zambia. The data show that since 2022, the lake level has dropped sharply.
The international Surface Water and Ocean Topography (SWOT) mission – led by NASA and the French space agency Centre National d’Études Spatiales (CNES) – has sent back some of its first glimpses of water on the planet’s surface, showing ocean currents like the Gulf Stream in unprecedented detail.
Dr. Wendy Bohon combines her passions for communication and science to help fellow NASA scientists learn how to better share their excitement for science with the world.
NASA research finds that a combination of windblown dust and human-caused particle pollution was associated with nearly 3 million premature deaths in 2019.
Observations from space show that the rate of sea level rise is increasing. Knowing where and how much rise is happening can help coastal planners prepare for future hazards. Since satellites began observing sea surface height in 1993 , the average global sea level has increased by 3.6 inches (9.1 cm), according to NASA’s Sea Level Change Team.
To honor and celebrate Women's History Month, this story focuses on the unique journey of one of NASA Goddard’s most versatile, adventurous, high-energy, and hard-working research scientists, Dr. Chelsea Parker — in her own words. Parker uses NCCS high-performance computing resources to study the atmosphere and ice in polar regions.
Scientists have predicted that droughts, floods will become more frequent and severe as our planet warms and climate changes, but measuring this on regional scales has proven difficult.
With the help of artificial intelligence and high-resolution satellite images, scientists mapped almost 10 billion individual trees in Africa’s drylands to assess the amount of carbon stored outside of the continent’s dense tropical forests. Having an accurate tree carbon estimate is essential for climate change projections.
