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.
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.
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.
It is the largest estuary in the United States and third largest in the world. Once sculpted and changed by ice, water, and powerful geologic forces over tens of millions of years, today's Bay is shaped by human forces as well.
A few decades ago, the idea of predicting a disease outbreak via satellite was science fiction. But today, researchers can use environmental data to predict when and where some diseases are likely to spread.
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.
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.
NASA satellites and sensors constantly take the pulse of our planet. Researchers apply those observations on local and regional scales to better manage things like food and water supplies, health, safety, land use, and ecosystems.
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.
