Students move through a series of short activities to explore and evaluate global solar radiation data from NASA satellites.  In this process, students make qualitative and quantitative observations about seasonal variations in net energy input to the Earth System.

Watch NASA videos about aerosols and volcanic ash.

Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.
