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.
Whether started by humans (farming, logging, or accidents) or by nature (lightning), fires are always burning somewhere on Earth. These maps show the locations of fires burning around the world each month.
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.
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.
Snow and ice influences 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.
Carbon flows between the atmosphere, land, and ocean in a cycle that encompasses nearly all life and sets the thermostat for Earth's climate. By burning fossil fuels, people are changing the carbon cycle with far-reaching consequences.
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.
One of the major rivers of Bangladesh has been growing in size, transforming in shape, and changing in location for decades. Each twist and zigzag of the river tells a different geologic story about the power of erosion.
These maps show the ‘metabolism” of Earth’s plants and trees. Net primary productivity is the difference between the amount of carbon dioxide absorbed during photosynthesis minus the amount released by respiration.
