Aerosol Size

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.

Vegetation

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.

Aerosol Optical Depth

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.

Your challenge is to tell us the location of the satellite image and why it is interesting.

Earth at Night

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.

How to Interpret a Satellite Image: Five Tips and Strategies

What do you do when presented with a new satellite image? Here's what the Earth Observatory team does to understand the view.

Remote Sensing

Renewable and Alternative Energy

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.

Land Human Presence

Air Quality

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.

Chlorophyll

Chlorophyll is used by algae and other phytoplankton--the grass of the sea--to convert sunlight and carbon dioxide into sugars. These maps show chlorophyll concentrations in the ocean, revealing where phytoplankton are thriving.
