NASA citizen scientists collected thousands of photographs and temperature readings that are being used to study the relationship between total solar eclipses and clouds.
NASA satellites are helping track tiger habitat, offering hope and new insights for conservation as these predators face the consequences of rapid habitat loss.
Land surface temperatures rise and fall with the heat of the Sun, and they represent how hot or cold the surface would feel to touch. These maps show daytime land temperatures as measured from space.
These maps depict monthly total rainfall around the world. Rainfall is the primary source of fresh water for humans, plants, and animals. Rain also moves heat between the atmosphere, oceans, and land.
Net radiation is the balance between incoming and outgoing energy at the top of the atmosphere. It is the total energy available to influence climate after light and heat are reflected, absorbed, or emitted by clouds and land.
Snow and ice influence climate by reflecting sunlight back into space. When it melts, snow is a source of water for drinking and vegetation; too much snowmelt can lead to floods. These maps show average snow cover by month.
When fuels such as coal, wood, and oil burn incompletely, they produce carbon monoxide. The gas is spread by winds and circulation. These maps show monthly averages of CO in the lower atmosphere.
Have you ever wondered what it would be like to live in a different part of the world? What would the weather be like? What kinds of animals would you see? Which plants live there? By investigating these questions, you are learning about biomes.
In honor of our site anniversary, we offer a selection of some of the most beautiful, newsworthy, interesting, and scientifically important images from 23 years online — one image for each day of the calendar year.
Satellite images of Earth at night have been a curiosity for the public and a tool of fundamental research for at least 25 years. They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness.
Sea salt, volcanic ash, dust, wildfire smoke, and industrial pollution are types of airborne aerosols. Natural aerosols tend to be larger than human-made aerosols. These maps show when and where aerosols come from nature, humans, or both.
