Science Connections 

What's new in NASA cloud science? Read the weekly roundup for the latest. How do your cloud observations connect to NASA's?

Cloudy Earth, from NASA’s Aqua satellite’s MODIS instrument shows an average of Earth’s cloud coverage between the years 2002 and 2015. There are three broad bands where cloud coverage is prevalent.  Can you find them? Do you also see where there are areas that do not receive much coverage? Read more.

Cloud Connections and Citizen Science

Jessica Taylor, cloud scientist and education specialist at NASA's Langley Research Center talks about why clouds are an important topic of scientific study and how your cloud observations are helping to answer questions about our planet's changing climate. Learn more about cloud science.

Meet the Scientist

Meet NASA cloud scientist, Lin Chambers, and learn how she uses citizen observations of clouds to interpret satellite data. 

NASA Missions

Many NASA missions study clouds from space, each adding a different perspective. Learn more about the satellites and what they measure.

GEOS-5 Models

Satellites see the planet from space, and scientists and citizen scientists measure clouds from the ground in a series of measurements like snapshots, but models connect all of the pieces like a movie. This helps us understand how clouds move, how they change, and how things like aerosols (tiny particles in the atmosphere) influence cloud formation. Learn more.

Fair Weather Cumulus

This is a fair weather cumulus scene over Pleasant Lake in New Hampshire. It is typical of summertime in the northern United States. Note that the cloud base is relatively high, as indicated by the fact that the clouds are higher than Mount Kearsarge (elev. 996 m; 753 m above the lake).
