Clouds Resource Library
Create a cloud collage and ask your friends to guess the percentage of cloud cover. Expand or adapt this activity by printing photos of the sky and asking participants to identify the cloud coverage.
See a video demonstration of Cloud Cover Estimation as a family activity.
Create a cloud using rubbing alcohol and an air pump and investigate it using a laser.
You can also do this demonstration using water, ice and a match.
Categorize various materials by opacity and understand why cloud opacity matters. Add a light sensor to measure how much light passes through the materials.
Create a sky scene using materials like wax paper, fabric and paper, and learn about the different characteristics of clouds.
Clouds or Snow: A Satellite Mystery
This issue of Earth Observatory for Kids explains how clouds and snow can look the same from a distance, and how satellites can tell the difference by measuring light that humans cannot see. The accompanying activity is "Make Your Own Cloud (In a Bottle)"
Watch a video demonstration of the cloud in a bottle activity.
[2:50] Learn about the shape of a raindrop and why it is important for satellites like GPM to be able to measure the size of a raindrop.
Correlation Between GLOBE Citizen Science and NASA Satellite Observations
[1:49] In this animation, data from Aqua, CALIPSO, CloudSat and GLOBE Observer are combined to show how multiple observations reveal the structure of clouds.
[2:01] This video provides examples of how rain affects our lives and explains how NASA uses satellites to study precipitation.
[2:35] This short video describes how to use the GLOBE Observer app to observe clouds and includes helpful tips.
[2:45] Atmospheric scientist, Jessica Taylor, describes how clouds affect our weather and climate and explains how your cloud observations help scientists study clouds.
NASA Behind the Science: Dr. Yolanda Shea
[9:59] Dr. Yolanda Shea shares how watching the weather forecast led her to a career as a NASA scientist. Dr. Shea uses remote sensing to study the role of clouds in Earth's climate.
[2:49] This video breaks down how much of Earth's water is usable and why studying precipitation is important for preparing for extreme weather, like flooding or drought.
Cloud Cover Estimation - Interactive
This interactive web-based tool allows you to calibrate your eye by practicing cloud cover estimation using images on the computer. (Requires Flash)
Cloud Type Practice - Interactive
This interactive web-based tool asks a series of questions to help you narrow down the type of cloud you are observing. It can be used both for practice and in the field to identify clouds. (Requires Flash)
Contrail Formation Tutorial - Interactive
In this tutorial, you can explore the physics of contrail formation in the atmosphere and develop the ability to recognize the several types of contrails that form under varying atmospheric conditions. Practice classifying the type and abundance of contrails. (Requires Flash)
[2:35] This short video describes how to use the GLOBE Observer app to observe clouds and includes helpful tips.
PDF version of the in-app tutorial, providing information to make an observation.
Cut out the rectangle in the middle of the Sky Window and use the information on the frame to help describe sky conditions and identify clouds.
