Clouds can be a nuisance when scientists are trying to observe features on Earth's surface. But at other times, clouds are exactly what they want to see. These images highlight some of the more unusual and beautiful clouds observed in recent years from space.
A Celebration of Clouds: From Space, Earth Has an Elegant Atmosphere
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.
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.
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.
NASA has a unique vantage point for observing the beauty and wonder of Earth and for making sense of it. The images in this book tell a story of a 4.5-billion-year-old planet where there is always something new to see.
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.
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.
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.
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.
For 20 years, astronauts have been shooting photos of Earth from the space station. Like everything the astronauts do, they are trained for this job. And like everything they do, there is purpose and intention behind it.
From their perch on the space station, astronauts have spent 20 years sharing a story about Earth as they see it from above. Like the directors of a film, those astronaut storytellers have a crew working behind the scenes to help them tell the story. Meet the Earth Science and Remote Sensing Unit.
