Welcome to NEO!
Our Mission
Our mission is to help you picture climate and environmental changes as they occur on our home planet. Here you can browse and download imagery of satellite data from NASA's constellation of Earth Observing System satellites. Read more
Atmosphere
Aerosol Optical Thickness
Tiny solid and liquid particles suspended in the atmosphere are called aerosols. Examples of aerosols include windblown dust, sea salts, volcanic ash, smoke from fires, and pollution from factories. These particles are important to scientists because they can affect climate, weather, and people’s health. Aerosols affect climate by scattering sunlight back into space and cooling the surface. Aerosols also help cool Earth in another way — they act like “seeds” to help form clouds. Read more
Energy
Solar Insolation
These maps show where and how much sunlight fell on Earth’s surface during the time period indicated. Scientists call this measure solar insolation. Knowing how much of the Sun’s energy reaches the surface helps scientists understand weather and climate patterns as well as patterns of plant growth around our world. Read more
Land
Land Surface Temperature Anomaly
Land surface temperature is how hot or cold the ground feels to the touch. An anomaly is when something is different from average. These maps show where Earth’s surface was warmer or cooler in the daytime than the average temperatures for the same week or month from 2001-2010. Read more
Life
Vegetation Index
Our lives depend upon plants and trees. They feed us and give us clothes. They absorb carbon dioxide and give off oxygen we need to breathe. Plants even provide many of our medicines and building materials. So when the plants and trees around us change, these changes can affect our health, our environment, and our economy. Read more
Ocean
Sea Surface Temperature
Sea surface temperatures influence weather, including hurricanes, as well as plant and animal life in the ocean. Read more

Goodbye, NEO
After over 20 years of continuous delivery of global NASA data imagery, NASA Earth Observations (NEO) is going to say goodbye on September 1, 2026.
