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.
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.
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.
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.
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.
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.
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.
These maps depict anomalies in land surface temperatures (LSTs); that is, how much hotter or cooler a region was compared to the long-term average. LST anomalies can indicate heat waves or cold spells.
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.
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.
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.
