NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or veteran) users of satellite data.
Can you tell El Nino from La Nina? This interactive was created by UCAR Center for Science Education using satellite images of the height of the ocean surface. Students interpret these images to identify whether they represent El Nino, La Nina, or neither event (La Nada!).
View a collection stunning images from around the world showing various ice forms. Find out why NASA studies ice from space.
El Niño is a condition that sometimes occurs in the Pacific Ocean, but it is so big that it affects weather all over the world. Weather depends a lot on ocean temperatures. Where the ocean is warm, more clouds form, and more rain falls in that part of the world.
Students review a video showing a global view of the top-of-atmosphere shortwave radiation from January 26 and 27, 2012 and answer the questions that follow.
Helping students build their understanding of Earth's spheres and how they are connected is difficult. Review the graphics to help identify the parts of the Earth System and the processes that connect them at the local, regional, and global scales.
Hurricanes are large, swirling storms with winds of 119 kilometers per hour (74 mph) or higher. That's quicker than a cheetah can run which is the fastest animal on land. They are said to be the most violent storms on Earth.
Learn more about the different causes of sea level change and the scientific background of observations and projecting sea level. Find out about the history of measuring sea level and how state-of-the-art physical climate models predict sea level change into the future.
