In this activity, students use satellite images from the NASA Landsat team to quantify changes in glacier cover over time from 1986 to 2018. 

Explore and connect to the GLOBE Water Quality protocol bundle. 

Explore and connect to the GLOBE Rivers and Lakes protocol bundle. 

Explore and connect to the GLOBE Oceans protocol bundle. 

Explore and connect to the GLOBE Mosquito protocol bundle. 

NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or veteran) users of satellite data.

Explore and connect to hydrosphere protocols in GLOBE. Each protocol has related Earth System Data Explorer datasets identified as well.

This activity is one of a series in the collection, The Potential Consequences of Climate Variability and Change activities. 

Students will analyze and interpret maps of the average net atmospheric radiation to compare the flow of energy from the Sun toward Earth in different months and for cloudy versus clear days. Students will draw conclusions and support them with evidence.
