Accessible to the intrepid boater, Washington state’s northern San Juan Islands include a marine state park with abundant natural beauty and geologic wonders.
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.
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.
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.
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.
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.
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.
In addition to making rain and snow, clouds can have a warming or cooling influence depending on their altitude, type, and when they form. These maps show what fraction of an area was cloudy each month.
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.
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.
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.
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.
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.
