Satellite data on cloud cover is used in this investigation to show the relationship between clouds and solar declination. Students will download data on declination angles along with data on clouds and cloud cover for a one-year time period.... (View More) Additional years will be added to the download in order to determine any seasonal patterns. Cloud cover near the equator is the focus of the analysis. This lesson uses student- and citizen science-friendly microsets of authentic NASA Earth system science data from the MY NASA DATA project. It also includes related links, extensions, and an online glossary. (View Less)
