The My NASA Data visualization tool, Earth System Data Explorer (ESDE), helps learners visualize complex Earth System data sets over space and time. Visit this page to review the datasets we have available to you and their organization by Earth System sphere, science variable, dataset name, and start/end dates. 

An important scientific practice is the asking and refining of questions that lead to rich descriptions, explanations, and reasoning of how the natural and designed world works, as well as those investigations of variables that can be empirically tested.

Background information on the El Nino Southern Oscillation or ENSO.

Explore and connect to the GLOBE Water Quality protocol bundle. 

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

Background information on snow and ice extent.

Explore and connect to the GLOBE ENSO (El Niño Southern Oscillation) protocol bundle. 

The activities in this guide will help students understand variations in environmental parameters by examining connections among different phenomena measured on local, regional and global scales.

Students explore positive feedback effects of changing albedo from melting Arctic sea ice.
