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.
Snow and ice influence 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.
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.
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 average amount of water vapor in a column of atmosphere by month. Water vapor is the key precursor for rain and snow and one of the most important greenhouse gases in the atmosphere.
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.
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.
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 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.
