A lunette dune fringing this dried Australian lake preserves relics from ancient times, while today’s grazing patterns create sharp visible contrasts on the land.
An astronaut’s sweeping nighttime photograph of Namibia and South Africa reveals the region’s lighted communities, many of which are centered around mining.
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.
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.
These maps depict how much hotter or cooler an ocean basin was compared to the long-term average. Temperature anomalies can indicate changes in ocean circulation or the arrival of patterns like El Niño and La Niña.
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.
Perth, the only city along the country’s western coastline with more than 1 million people, displays widespread urban infrastructure alongside the Swan and Canning rivers.
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.
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.
People have developed systems to harvest and store energy from sources such as wind, sunlight, and tidal action. Many of these installations are visible from orbit.
From ground-level ozone to particulate matter to nitrogen dioxide, an array of gasses and particles can affect the air people breathe, with implications for human health.
Greenness is an important indicator of health for forests, grasslands, and farms. The greenness of a landscape, or vegetation index, depends on the number and type of plants, how leafy they are, and how healthy they are.
Whether sparked by lightning, intentional land-clearing, or human-caused accidents, wildland fires are burning longer and more often in some areas as the world warms.
Airborne aerosols can cause or prevent cloud formation and harm human health. These maps depict aerosol concentrations in the air based on how the tiny particles reflect or absorb visible and infrared light.
